I have renewed my Microsoft Certified Trainer certification for 2021-2022. The big requirement was to teach a MOC class during the calendar year and get the MTM surveys in the system to be able to renew. Most Microsoft employees renew internally, but I am currently NOT working for Microsoft. I was able to get the classes taught so that I was able to renew for the new year.
Microsoft Certified Trainer 2021-2022
I am still available for music performance through my company but the IT Side of the business has been closed as I am on a full time project and cannot devote any outside time to IT consulting. Thank everyone for supporting me over the years. My blog will still remain current so please check here often for the latest updates for Exchange, M365, Security, Compliance, and Windows!
This was a great article released by the Exchange Team Blog today, and as I have been dealing with MANY customers still having Exchange 2010, I wanted to have this available for quick review! It has great links and steps to consider when finally getting off Exchange 2010.
As many of you know from the previous post regarding Exchange On-Premises Best Practices for Migrations from 2010 to 2016 the end of support for Exchange 2010 is quickly approaching. We’ve created this post to cover the best practices for decommissioning an Exchange 2010 environment after the migration has completed.
Uninstalling Exchange 2010 is as easy as running Setup and selecting to remove the server roles, but there are prerequisites to removing the roles and legacy items left over, which should be removed.
This post is intended to provide best practices to plan for and complete the Exchange 2010 decommission. Please note that since there are many different types of deployments and configurations it is difficult to cover all scenarios, but many of the common steps are included here. Please plan the decommission process carefully.
As a general statement, here are some things that we want to caution against:
This post assumes that your organization is maintaining some Exchange presence on-premises, whether Exchange 2013 or 2016 (we do not mention Exchange 2019 in this post because it cannot coexist with Exchange 2010). If your organization has moved all mailboxes to Office 365 and is in a Hybrid environment, we are assuming you will maintain an Exchange footprint per Scenario 2 in How and when to decommission your on-premises Exchange servers in a hybrid deployment.
Once you’ve completed the migration from Exchange 2010 to, let’s say, Exchange 2016, you should prepare the 2010 environment prior to decommissioning the servers. The following steps to consider are separated into server roles when preparing for a soft shut down and preparing for the removal of server roles.
Review all namespaces (e.g. DNS records and load balanced virtual IP addresses) used for client connectivity and ensure they are routing to the 2016 environment. These are all the names that are published for Outlook Anywhere, AutoDiscover, and all Exchange Virtual Directories.
Tip: Verify that all clients such as ActiveSync, Outlook, EWS, OWA, OAB, POP3/IMAP, and Autodiscover are no longer connecting to the legacy Exchange servers. Verification of this can be done by reviewing the servers’ IIS Logs with Log Parser Studio (LPS). LPS is a GUI for Log Parser 2.2 and it greatly reduces the complexity of parsing logs. LPS can parse large sets of logs concurrently (we have tested with total log sizes of >60GB). Please refer to the following blog post with tips and information on using LPS.
Make sure that the Service Connection Point (SCP) is moved to Exchange 2016 as discussed in the Exchange On-Premises Best Practices for Migrations from 2010 to 2016 post under the Configure Autodiscover SCP for Internal Clients section.
1 | Get-ExchangeServer | ? {$_.AdminDisplayversion -like "Version 14.*" -and $_.IsClientaccessServer -eq $true} | Get-ClientAccessServer | Select Name, FQDN, AutoDiscoverServiceInternalUri |
If present, ensure that if the AutoDiscoverServiceInternalURI routes to an Exchange 2016 endpoint. You can also remove this value by setting the AutoDiscoverServiceInternalURI to $Null.
1 | Set-ClientAccessServer -Identity <Exchange2010> -AutoDiscoverServiceInternalURI https://autodiscover.contoso.com/AutoDiscover/AutoDiscover.xml |
Follow the items below to review all mail flow connectors. We will not be removing connectors themselves, simply auditing to ensure that the server is ready to be decommissioned.
Review the send connectors and ensure that the legacy servers have been removed and Exchange 2016 servers have been added. Most organizations only permit outbound network traffic on port 25 to a small number of IP addresses, so you may also need to review the outbound network configuration.
1 2 | Get-SendConnector | Select Name,SourceTransportServers Get-ForeignConnector | Select Name,SourceTransportServers |
Review the receive connectors on legacy servers and ensure they are recreated on your Exchange 2016 servers (e.g. SMTP relay; anonymous relay; partner, etc.). Review all namespaces (e.g. DNS records and load balanced virtual IP addresses) used for inbound mail routing and ensure they are terminating against the Exchange 2016 environment. If your legacy Exchange servers have any custom, third-party, or foreign connectors installed (for example, with fax services), ensure that they can be reinstalled on 2016 Exchange servers.
1 | Get-ReceiveConnector -Server <ServerToDecommission> |
Tip: Check the SMTP logs to see if any outside systems are still sending SMTP traffic to the servers via hard coded names or IP addresses. To enable logging, review Configure Protocol Logging. Also, ensure we have “time coverage” for any apps relaying weekly/monthly emails that may not be caught in a small sample size of SMTP Protocol logs. There is a great script available here that can help find any applications that may be relaying off your legacy environment.
In general, the decommissioning process is a great time to audit your mail flow configuration to ensure that all the connectors are properly configured and secured. Maybe it’s time to get rid of any of those Anonymous Relay connectors that may be in use in your environment. Or, if Hybrid, possibly relay against Office 365.
Exchange 2010 base transport rules are held in a different AD container than Exchange 2013 and newer rules. When installing Exchange 2016 in your environment it will import those Exchange 2010 based rules. However, any changes to Exchange 2010 rules after a later version of Exchange is installed must also be applied to your Exchange 2016 rules. This is further explained here under section Coexistence with Exchange 2010.
Run the following command to get all your Exchange Transport Rules. Must be run on Exchange 2016 to see all rules.
1 | Get-TransportRule | Select Name,RuleVersion |
Compare the rules with RuleVersion of 14.X.X.X to those with 15.1.X.X. If any Exchange 2010 rules don’t exist on Exchange 2016, they must be created. Also review all settings of each Exchange 2010 rule and replicate them to Exchange 2016.
Decommissioning Exchange 2010 cannot be initiated until all mailboxes have been moved to Exchange 2016. As an example, we cannot decommission Exchange 2010 Hub Transport servers completely until all of the mailboxes are moved off the legacy platform, this is due to how Delivery Groups are handled.
We encourage using the newest Exchange platform to process any move requests. If moving to Exchange 2016, move all mailboxes via Exchange 2016. Also, ensure that once all moves are completed, and that all associated Move Requests are removed as well. Any lingering move requests or mailboxes will prevent uninstallation of Exchange 2010.
To move all user mailboxes, run the following command to identify the mailboxes, and then plan to move them to the new platform.
1 | Get-MailboxDatabase -Server <ServerToDecommission> | Get-Mailbox |
Tip: Ensure that Archives are included with “Get-Mailbox -Archive” if you used Exchange Archives in 2010. Also, do not forget about your Discovery Search mailboxes – these can be found with: Get-Mailbox -Filter { RecipientTypeDetails -eq “DiscoveryMailbox”}. These will need to be moved (if they haven’t yet already), to Exchange 2016 as well.
It’s necessary to move the arbitration mailboxes from Exchange 2010 to 2016 for many Exchange Services to work properly, including the Exchange Admin Center (EAC). This is typically executed when Exchange 2016 is first installed, however, if that was missed, we will ensure that is handled now. The process to move is defined at: Move the Exchange 2010 system mailbox to Exchange 2013+. To verify which system mailboxes are located on 2010, use PowerShell on your Exchange 2010 server with the following example:
1 | Set-ADServerSettings -ViewEntireForest $true Get-MailboxDatabase -Server <ServerToDecommission> | Get-Mailbox -Arbitration |
Note: If any mailboxes are present, move them to an Exchange 2016 database.
Installing first Exchange Server 2013+ into Exchange 2010 organization creates a new OAB. It also marks the new OAB as default. The Exchange 2010 OAB is not used by Exchange 2013+ servers so moving the OAB is not necessary. Move the OAB to another Exchange 2010 server, if you are removing an Exchange 2010 server that’s currently hosting the OAB, and there are other Exchange 2010 servers in the org. If you are removing the last Exchange 2010 server in the org, remove the OAB.
Verify that all the public folders have been migrated to Exchange Online, Office 365 Groups, or Exchange Modern public folders.
If the following is true:
In that case, you may need to run the SetMailPublicFolderExternalAddress.ps1 script to ensure Exchange 2013+ servers can continue sending emails to Exchange Online MEPFs.
Assuming best practices were followed for the Exchange 2010 environment, we will have a DAG for HA/DR capabilities. Now that all mailboxes have been removed from the 2010 environment, we are ready to tear down this DAG to move forward with decommissioning Exchange 2010.
First, we start with the copies. For every mailbox database copy in the environment hosted on Exchange 2010, we will need to remove the Mailbox Database Copy. This can be done via the UI, or via PowerShell:
1 | Remove-MailboxDatabaseCopy -Identity <DatabaseName>\<ServerToDecommission> -Confirm:$False |
NOTE: Removing the copy will not remove the actual .edb database file from the Server.
For each Exchange 2010 server in the environment, we will need to remove the individual server from the DAG. This is evicting the server from the cluster. This can be done via the UI, or through PowerShell.
1 | Remove-DatabaseAvailabilityGroupServer -Identity <DAGName> -MailboxServer <ServerToDecommission> |
Lastly, once the Database copies are removed, and the servers are evicted from the cluster, the last thing is to finally remove the DAG from the environment. This can be done with the following PowerShell command:
1 | Remove-DatabaseAvailabilityGroup -Identity <DAGName> -Confirm:$False |
Tip: If you have an even-membered DAG, and leveraged a File Share Witness, don’t forget to decommission the file share witness that was used for the Exchange 2010 DAG.
Configuration steps are required to move Exchange 2010 UM to Exchange 2016 servers. The following link can be used to guide through removal of UM from Exchange 2010. If moving to a third-party UM solution, remove the UM components to allow un-installation of the UM role.
If you have an Edge server, you will need to install Exchange 2016 Edge and recreate the Edge Subscription on the E2016 server. This is further documented here.
As mentioned in the beginning of the document, due to so many different types of deployments and configurations, it’s difficult to cover all scenarios however it’s recommended to check any other possible scenarios that apply to your environment.
Make a list of applications that may be using Exchange 2010 (e.g. EWS, mail transport, database-aware) and make sure to configure these applications to start using Exchange 2016 infrastructure.
Test shutting down the Exchange servers for a few days to a few weeks to see if there are any issues. You are auditing for any applications that are trying to connect to the Exchange 2010 servers or trying to send email through the Exchange 2010 servers. Enabling protocol logging on the Hub Transport roles prior to shutting down the servers is an option. That way if any mail is processing through these servers, upon restart, the logging will begin immediately. If applications or servers are trying to connect you can remediate those or power on the Exchange 2010 servers until remediation can happen.
Tip: Check Active Directory DNS Zone settings to see if DNS Scavenging is enabled. If this is enabled, the DNS record could become stale during the shutdown time frame and cause DNS issues for the Exchange 2010 server.
As you begin the process of removing servers, you should go through the list below and ensure you have everything tested and ready to go.
Remove Any Exchange 2010 Client Access Arrays from Active Directory and DNS. Refer to the following document to remove the Client Access Array object with Shell using the following example:
1 | Remove-ClientAccessArray -Identity casarray01.contoso.com |
Be sure to also remove any references in DNS to the CAS Array Name.
If you followed either the Best practices for Migrations blog or the Coexistence with Kerberos blog, we recommend that any old alternate service accounts (ASAs) used for E2010 be removed. If you are using a different namespace than Exchange 2016, please verify old SPNs are also removed.
Use the following command to remove Exchange 2010 OAB:
1 | Get-OfflineAddressBook | ?{$_.ExchangeVersion -like "*14*"} | Remove-OfflineAddressBookMailbox |
Now that all mailboxes are migrated from the Exchange 2010 platform, and the DAG is properly removed, we will want to decommission any leftover databases from the Exchange 2010 environment. To remove all Exchange 2010 databases, review the output of the following, and remove individually:
1 | Get-MailboxDatabase -Server <ServerToDecommission> |
And then remove the database with:
1 | Remove-MailboxDatabase -Identity DB1 |
NOTE: If there are any mailboxes currently residing on the database, we will not let you remove the database, it will fail with the following error:
If you chose not to migrate public folders, refer to the following document to remove public folders with either EMC or Shell using the following example:
Refer to the following document to remove the public folder databases with PowerShell using the following example:
1 | Remove-PublicFolderDatabase -Identity "PFDB01" |
Tip: Remember the .edb files linger after the above is done. Feel free to delete, backup, or do with these as you please.
It’s recommended to uninstall in the following order: CAS, Hub, UM (if any), then Mailbox.
When you begin the uninstall process, close EMC, EMS, and any additional programs that could delay uninstall process (i.e. programs using .NET assemblies; antivirus and backup agents are examples). You can either run Exchange 2010 Setup.exe or navigate to Control Panel to modify or remove Exchange 2010 (either server roles or the entire installation). Specific steps are discussed in Modify or Remove Exchange 2010.
Tip: Exchange will protect itself! If you properly uninstall via Add/Remove Programs, it will ensure that it is ready to be uninstalled via Readiness Checks! If all the above prep work is completed before hand, it should uninstall just fine.
After uninstalling Exchange there will be some general “housekeeping” tasks. These may vary depending on the steps taken during your upgrade and depending on your organization’s operational requirements.
Examples include:
With the uninstall of the last server, hopefully Exchange 2010 treated your organization well. The Exchange product team takes great pride of the success of the platform and hope that you see the same success with Exchange 2016 (or Exchange Online!). Messaging sure has come a long way since it was released way back in 2009.

I get asked this a lot in my travels, “What’s the difference with Exchange 2019 and why should we go to it other than the fact that it is the latest version released. I wanted to post my findings from articles that I found to help explain some of the improvements and differences with running Exchange 2019.
Exchange Server 2019 brings a new set of technologies, features, and services to Exchange Server, the messaging platform that provides email, scheduling, and tools for custom collaboration and messaging service applications.
There are some things that have been discontinued in Exchange 2019 which make the decision to go to it important for some companies.
| Feature | Comments and mitigation |
|---|---|
| Unified Messaging (UM) | Unified Messaging has been removed from Exchange 2019. We recommend that Exchange 2019 organizations transition to Skype for Business Cloud Voice Mail. |
This is a big deal for some companies as they rely on Unified Messaging to handle their Voice Messaging. There are some articles available to view to assist in transitioning from UM to the new voicemail features with O365. I will post them as I find them in this blog. Keep tuned in for updates!
Here are some other deprecated features:
| Client Access server role | The Client Access server role has been replaced by Client Access services that run on the Mailbox server role. The Mailbox server role now performs all functionality that was previously included with the Client Access server role. For more information about the new Mailbox server role, see Exchange Server architecture. |
| MAPI/CDO library | The MAPI/CDO library has been replaced by Exchange Web Services (EWS), Exchange ActiveSync (EAS), and Representational State Transfer (REST)* APIs. If an application uses the MAPI/CDO library, it needs to move to EWS, EAS, or the REST APIs to communicate with Exchange 2019. |
The following features are being de-emphasized in Exchange 2019 and may not be included in future versions of Exchange.
Today, CPU horsepower is significantly less expensive and is no longer a constraining factor. With that constraint lifted, the primary design goal for Exchange 2019 is for simplicity of scale, hardware utilization, and failure isolation. With Exchange 2019, we reduced the number of server roles to two: the Mailbox and Edge Transport server roles.
Unified Messaging (UM) has been removed from Exchange 2019. Other than that, the Mailbox server in Exchange 2019 includes all of the server components from the Exchange 2013 Mailbox and Client Access server roles:
The Edge Transport role is typically deployed in your perimeter network, outside your internal Active Directory forest, and is designed to minimize the attack surface of your Exchange deployment. By handling all Internet-facing mail flow, it also adds additional layers of message protection and security against viruses and spam, and can apply mail flow rules (also known as transport rules) to control message flow.
For more information about the Exchange 2019 architecture, see Exchange architecture.
Along with the new Mailbox role, Exchange 2019 now allows you to proxy traffic from Exchange 2013 Client Access servers to Exchange 2019 mailboxes. This new flexibility gives you more control in how you move to Exchange 2019 without having to worry about deploying enough front-end capacity to service new Exchange 2019 servers.
MAPI over HTTP is now the default protocol that Outlook uses to communicate with Exchange. MAPI over HTTP improves the reliability and stability of the Outlook and Exchange connections by moving the transport layer to the industry-standard HTTP model. This allows a higher level of visibility of transport errors and enhanced recoverability. Additional functionality includes support for an explicit pause-and-resume function, which enables supported clients to change networks or resume from hibernation while maintaining the same server context.
Note: MAPI over HTTP isn’t enabled in organizations where the following conditions are both true:
While MAPI over HTTP is now the default communication protocol between Outlook and Exchange, clients that don’t support it will fall back to Outlook Anywhere (RPC over HTTP).
Outlook Web App is now known as Outlook on the web, which continues to let users access their Exchange mailbox from almost any web browser.
NOTE: Supported Web browsers for Outlook on the web in Exchange 2019 are Microsoft Edge, Internet Explorer 11, and the most recent versions of Mozilla Firefox, Google Chrome, and Apple Safari.
The former Outlook Web App user interface has been updated and optimized for tablets and smart phones, in addition to desktop and laptop computers. New Exchange 2019 features include:
Exchange 2019, along with SharePoint Server 2019 and SharePoint Online, enables Outlook on the web users to link to and share documents that are stored in OneDrive for Business in an on-premises SharePoint server instead of attaching files to messages. Users in an on-premises environment can collaborate on files in the same manner that’s used in Office 365.
When an Exchange 2019 user receives a Word, Excel, or PowerPoint file in an email attachment, and the file is stored in OneDrive for Business or on-premises SharePoint, the user will now have the option of viewing and editing that file in Outlook on the web alongside the message. To do this, you’ll need a separate computer in your on-premises organization that’s running Office Online Server.
Exchange 2019 also brings the following improvements to document collaboration:
The Hybrid Configuration Wizard (HCW) that was included with Exchange 2013 is moving to become a cloud-based application. When you choose to configure a hybrid deployment in Exchange 2019, you’ll be prompted to download and install the wizard as a small app. The wizard will function the same in previous versions of Exchange, with a few new benefits:
In addition to Hybrid Configuration Wizard improvements, multi-forest hybrid deployments are being simplified with Azure Active Directory Connect (AADConnect). AADConnect introduces management agents that will make it significantly easier to synchronize multiple on-premises Active Directory forests with a single Office 365 tenant.
Exchange ActiveSync clients will be seamlessly redirected to Office 365 when a user’s mailbox is moved to Exchange Online. To support this, ActiveSync clients need to support HTTP 451 redirect. When a client is redirected, the profile on the device is updated with the URL of the Exchange Online service. This means the client will no longer attempt to contact the on-premises Exchange server when trying to find the mailbox.
To comply with business standards and industry regulations, organizations need to protect sensitive information and prevent its inadvertent disclosure. Examples of sensitive information that you might want to prevent from leaking outside your organization include credit card numbers, social security numbers, health records, or other personally identifiable information (PII). With a DLP policy and mail flow rules (also known as transport rules) in Exchange 2019, you can now identify, monitor, and protect 80 different types of sensitive information with new conditions and actions:
Exchange 2019 includes the following improvements to In-Place Archiving, retention, and eDiscovery to help your organization meet its compliance needs:
In Exchange 2019, the search architecture has been redesigned. It is now based on the same engine as the modern search engines are and is directly on the mailbox in Exchange 2019. There is no content index database attached to the mailbox database as in previous versions of Exchange Server. Previously, search was a synchronous operation that was not very fault-tolerant. The new architecture is asynchronous and decentralized. It distributes the work across multiple servers and keeps retrying if any servers are too busy. This means that we can return results more reliability, and faster.
Another advantage of the new architecture is that search scalability is improved. The number of mailboxes you can search at once using the console has increased from 5k to 10k for both mailboxes and archive mailboxes, allowing you to search a total of 20k mailboxes at the same time.

Microsoft has released security updates for vulnerabilities found in:
These updates are available for the following specific builds of Exchange Server:
IMPORTANT: If manually installing security updates, you must install .msp from elevated command prompt (see Known Issues in update KB article).
Vulnerabilities addressed in the April 2021 security updates were responsibly reported to Microsoft by a security partner. Although we are not aware of any active exploits in the wild, our recommendation is to install these updates immediately to protect your environment.
These vulnerabilities affect Microsoft Exchange Server. Exchange Online customers are already protected and do not need to take any action.
For additional information, please see the Microsoft Security Response Center (MSRC) blog. More details about specific CVEs can be found in Security Update Guide (filter on Exchange Server under Product Family).
Two update paths are:
Use the Exchange Server Health Checker script, which can be downloaded from GitHub (use the latest release), to inventory your servers. Running this script will tell you if any of your Exchange Servers are behind on updates (CUs and SUs).
Go to https://aka.ms/ExchangeUpdateWizard and choose your currently running CU and your target CU. Then click the “Tell me the steps” button, to get directions for your environment.
Make sure to follow the ExchangeUpdateWizard instructions and best practices for installation of updates carefully, including when to install using elevated command prompt. If you encounter errors during or after installation, see Repair failed installations of Exchange Cumulative and Security updates.
My organization is in Hybrid mode with Exchange Online. Do I need to do anything?
While Exchange Online customers are already protected, the April 2021 security updates do need to be applied to your on-premises Exchange Server, even if it is used only for management purposes. You do not need to re-run the Hybrid Configuration Wizard (HCW) after applying updates.
Do the April 2021 security updates contain the March 2021 security updates for Exchange Server?
Yes, our security updates are cumulative. Customers who installed the March 2021 security updates for supported CUs can install the April 2021 security updates and be protected against the vulnerabilities that were disclosed during both months. If you are installing an update manually, do not double-click on the .msp file, but instead run the install from an elevated CMD prompt.
Is Microsoft planning to release April 2021 security updates for older (unsupported) versions of Exchange CUs?
No, we have no plans to release the April 2021 security updates for older or unsupported CUs. In March, we took unprecedented steps and released SUs for unsupported CUs because there were active exploits in the wild. You should update your Exchange Servers to supported CUs and then install the SUs. There are 47 unsupported CUs for the affected versions of Exchange Server, and it is not sustainable to release updates for all of them. We strongly recommend that you keep your environments current.
Can we use March 2021 mitigation scripts (like EOMT) as a temporary solution?
The vulnerabilities fixed in the April 2021 updates are different from those we fixed before. Therefore, running March 2021 security tools and scripts will not mitigate the vulnerabilities fixed in April 2021. You should update your servers as soon as possible.
Do I need to install the updates on ‘Exchange Management Tools only’ workstations?
Servers or workstations running only Microsoft Exchange Management Tools (no Exchange services) do not need to apply these updates.
Why are there security updates two months in a row?
Microsoft regularly releases Exchange Server security updates on ‘patch Tuesday’. We are always looking for ways to make Exchange Server more secure. You should expect us to continue releasing updates for Exchange Server in the future. The best way to be prepared for new updates is to keep your environment current.
Is there no update for Exchange Server 2010?
No, Exchange 2010 is not affected by the vulnerabilities fixed in the April 2021 security updates.
Is there a specific order of installation for the April 2021 security updates?
We recommend that you update all on-premises Exchange Servers with the April 2021 security updates using your usual update process.

I always have issues getting my certificate renewed using OpenSSL and the certificates that GoDaddy lets you download. I chose IIS and I chose Exchange Server in the GoDaddy download section of the site to get the CRT file. The issue I always have is converting it to PFX so that I can install it with a private key on my IIS Server. This is also relevant if you are using Azure to host your certificates as Microsoft requires PFX certificates in that realm.
So finally after I get it working today, I wanted to write this blog post to make sure I at least have a sure method to get the certificate converted with the private key. NOTE that this is for a certificate that has NOT expired.
First, download your certificate from GoDaddy to the server you have OpenSSL installed on.
Next, extract the cert to your directory and note the path. You will use the path in your OpenSSL cmdlet.
You may be seeing other files in there. Well the issue was that I couldn’t generate the proper private key and the PEM file given by GoDaddy did not work in the conversion. So, here is what I had to do on the Web Server to export the proper private key:
In the MMC Certificate Utility, export the current certificate with the private key:
Next, run the following cmd in OpenSSL to extract the private key from the exported certificate. Enter the password you created during the export when prompted:
1 | openssl pkcs12 -in c:\path\exportedwithpkey.pfx -nocerts -out c:\path\key.pem -nodes |
Next, use that key file along with the CRT file to create the new PFX. Enter the password again when prompted:
1 | openssl pkcs12 -export -out c:\path\newldlnet2021.pfx -inkey c:\path\key.pem -in c:\path\ldlnet2021.crt |
You should now have the proper NEW PFX file to import into IIS or Azure or where ever you need to the certificate installed with the private key! DON’T forget your password!

I like to post the Exchange Server CU Updates when they are released by the Exchange Team. It is important to keep up to date with the Exchange Updates especially after the Zero Day threat that came out the early part of March. Thank you for your continued reading and patronage!
Today we are announcing the availability of quarterly servicing cumulative updates (CUs) for Exchange Server 2016 and Exchange Server 2019. These CUs include fixes for customer reported issues as well as all previously released security updates. Although we mentioned in a previous announcement that this release would be the final cumulative update for Exchange 2016, we do expect to release one more CU for Exchange 2016 next quarter which will includes all fixes made for customer reported and accepted issues received before the end of mainstream support.
A full list of fixes is contained in the KB article for each CU, but we wanted to highlight that these latest CUs contain the fixes that were previously released as Exchange Server Security Updates on March 2, 2021. This means you don’t have to install the March 2021 Security Updates after installing the March 2021 CUs.
The KB articles that describe the fixes in each release and product downloads are as follows:
Microsoft recommends all customers test the deployment of any update in their lab environment to determine the proper installation process for your production environment. These updates contain schema and directory changes and so require you prepare Active Directory (AD) and all domains. You can find more information on that process here.
Also, to prevent installation issues you should ensure that the Windows PowerShell Script Execution Policy is set to Unrestricted on the server being upgraded or installed. To verify the policy settings, run the Get-ExecutionPolicy cmdlet from PowerShell on the machine being upgraded. If the policies are NOT set to Unrestricted you should use these resolution steps to adjust the settings.
Additionally, a reminder that if you plan to install any Cumulative Update using the unattended option with either PowerShell or Command Prompt, make sure you specify either the full path to the setup.exe file or use a “.” in front of the command if you are running it directly from directory containing the update. If you do not the Exchange Server Setup program may indicate that it completed successfully when it did not. Read more here.
Reminder: Customers in hybrid deployments where Exchange is deployed on-premises and in the cloud, and those using Exchange Online Archiving with their on-premises Exchange deployment are required to deploy the currently supported CU for the product version in use.
For the latest information on the Exchange Server and product announcements please see What’s New in Exchange Server and Exchange Server Release Notes.
Note: Documentation may not be fully available at the time this post is published.

This article came out in February and I have been behind on my blog updates due to my current project, but I feel this post is important and am going to relay the message that I received here for your review. Thanks again for your support of this blog and its continued longevity.
Microsoft periodically refreshes certificates in Office 365 as part of our effort to maintain a highly available and secure environment. From Jan 23rd, 2021, we are making a certificate change on our Microsoft Federation Gateway every six weeks that could affect some customers as detailed in this knowledge base article. Please note that longer term, this “six week” rhythm to renew the certificate will be further shortened to daily renewals which will further enhance security of the environment. The good news is you can easily avoid any disruption.
This certificate change can affect any customer that is using the Microsoft Federation Gateway (MFG). If you are in a hybrid configuration that relies on a Federation Trust established with MFG in the Exchange on-premises organization or if you are sharing free/busy information between two different on-premises organizations using the Microsoft Federation Gateway as a trust broker, you need to take action.
The change is scheduled to occur every six weeks to begin with, with this frequency further increasing. You must take action to avoid any disruptions.
If you don’t take action, you won’t be able to use services that rely on the Microsoft Federation Gateway. For example:
Additionally, if you run the Test-FederationTrust cmdlet, you might receive an error message that indicates that the Delegation token has validation issues. For example, you receive an error message that resembles the following:
Id : TokenValidation
Type : Error
Message : Failed to validate delegation token.
And, you might receive one of the following error messages in the Exchange Web Services (EWS) responses:
An error occurred when processing the security tokens in the message
Autodiscover failed for email address User@contoso.com with error System.Web.Services.Protocols.SoapHeaderException: An error occurred when verifying security for the message
You can use the following command on your Exchange Server to create a scheduled task to run the update process daily. This is how we recommend you keep your Federation Trust constantly updated. This will prevent you from being negatively affected by future metadata changes.
1 | Schtasks /create /sc Daily /tn FedRefresh /tr "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command Add-PSSnapIn Microsoft.Exchange.Management.PowerShell.E2010 ; $fedTrust = Get-FederationTrust ; Set-FederationTrust -Identity $fedTrust.Name -RefreshMetadata" |
If you prefer to not use a scheduled task, you can manually run the command at any time to refresh the metadata. This is not recommended as the frequency to refresh certificate will increase from 6 week period to daily, and manually updating this would be quite cumbersome.
1 | Get-Federationtrust | Set-FederationTrust –RefreshMetadata |
Please note that we have seen some situations where this command should be run twice to ensure it is successful.

There was a zero day threat in Exchange recently and I wanted to put out this update that I received from the Microsoft team so that it would be available to my followers and readers. I will try to keep this updated as much as I can as I am not updating my blog as much with my current projects taking up most of my time. Thanks to everyone and keep in touch!
To help customers more quickly protect their environments in light of the March 2021 Exchange Server Security Updates, Microsoft is producing an additional series of security updates (SUs) that can be applied to some older (and unsupported) Cumulative Updates (CUs). The availability of these updates does not mean that you don’t have to keep your environment current. This is intended only as a temporary measure to help you protect vulnerable machines right now. You still need to update to the latest supported CU and then apply the applicable SUs. If you are already mid-update to a later CU, you should continue with that update.
With these new updates, you will have a new path you can take:
These additional updates are about to be to available in KB5000871.
IMPORTANT: You must install .msp updates from elevated command prompt (see Known Issues in the update KB article)
If you install these additional updates, please ensure that you continue to bring your Exchange environment to supported state as soon as possible. Our original announcement Released: March 2021 Exchange Server Security Updates contains information and resources that can help you plan your updates, troubleshoot problems, and help you with mitigations, investigation, and remediation of the vulnerabilities.
To aid defenders in investigating these attacks where Microsoft security products and tooling may not be deployed, we are releasing a feed of observed indicators of compromise (IOCs). The feed of malware hashes and known malicious file paths observed in related attacks is available in both JSON and CSV formats at the below GitHub links. This information is being shared as TLP:WHITE.
Please keep checking the below blog post for any related updates.

Over the past few weeks, I have been doing my own deep dive study into MIP/AIP. I was looking at the following article:
Which PDF readers are supported for protected PDFs?
This article said that the later versions of the Edge Browser should natively be able to open and view MIP UL Protected PDF documents:
So I proceeded to do a Edge browser check on my Windows 10 test machine:
Great! I should be able to protect a PDF file as Confidential, and then be able to open it in Edge with no other software required.
This was NOT the case.
I protected the PDF:
I waited a few minutes and then tried to open the file. I received the following error:
Another issue with this error is that I did not receive the standard issued AIP Protection error that you should get like you would when opening a protected document without the proper plug-in with Adobe Reader:
The error in Edge said to check ownership permissions, which I did:
I could also go back into the AIP/MIP client and remove the Confidential label from the file. So, I was puzzled at this point. I then proceeded to install Adobe Reader DC and the AIP Plug-In as described in the original article.
Download MIP Adobe Plug-In
Once that was completed, I was able to logon as the account, open the document in Adobe Reader DC AND in Edge.
According to the article, you should not need the plug in or any other product to open the protected file in Edge after protection is applied. Has anyone else experienced this issue and can explain why the article is not doing as said. I would love to hear any answers you may have on this subject!

There is a current BUG is has been filed with Microsoft that relates to AIP/MIP Scanner and running a Unified Labeling content scan on premises. The main issue is with the Security and Compliance Center and it replicating the Policies that you create for your Sensitivity Labels in your M365 Tenant.
Since these Policies will not replicate, your content scans will fail and you will see the following error within the Azure Portal under Azure Information Protection:
You will be able to verify that the Policies are present in the Security and Compliance Center under the Information Protection page and the Policies Page in Azure Information Protection:
NOTE: I had created my labels and label policies in Azure AIP and migrated them to Security and Compliance Center via the following LINK
What you will also notice, if you create a policy in SCC, it will NOT replicate to Azure.
Next, I checked to see if the AIP Scanner Service Account has the policies applied to it as a member recipient of the policies. It needs to so that the account can apply labels to on premises accounts through the policy.
The AIP Scanner account was a member of a defined policies in the Security & Compliance Center and you are still having issues:
1 | Get-AIPScannerStatus | fl |
It says it is scanning, but you are not getting results AND you have that Error: Policy is missing statement in the Nodes Tab of AIP.
The next thing to verify this whether or not the policy is replicating from SCC to Azure. This is done through PowerShell by running the following:
Connect to SCC PowerShell
1 2 3 4 5 6 7 | $userCredential = get-credential Write-Host "Connecting to your Security and Compliance Center PowerShell Console" $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.compliance.protection.outlook.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection Import-PSSession $Session -DisableNameChecking |
Check the policy replication status
1 | Get-labelpolicy | select-object Name,DistributionStatus,WhenCreated,WhenChanged | FL |
Normal replication is up to 24 hours for a change or policy addition. So, if your WhenChanged or WhenCreated values are more than 24 hours old, then they are NOT replicating. You can further verify this by running the following:
1 | get-labelpolicy -identity "Name of your Policy" | fl DistributionResults,LastStatusUpdateTime |
If you have this error, it would be best to log a support call with Microsoft and explain that you have the AIP UL Policy Replication Error. From my sources they are saying this is a known issue with the SCC and Azure that will be remediated by the end of October.
So, in the meantime, I guess we will wait!
After troubleshooting with this issue with some of my Microsoft Colleagues, I was able to get the Scanner to start scanning properly with out the error being listed in the Azure Portal. Here are the steps.
On the scanner node, right-click a file or folder and choose to protect it:
Next, within the AIP Application, choose Help and Feedback
Next, choose Reset Settings
Click Continue
Once completed, click Close, then exit the AIP application. This clears all the registry settings within the scanner node.
Now you will want to reset all the local files for the scanner
First, stop the scanner services for the scanner and network discovery
1 2 3 | Stop-Service AIPScanner Stop-Service AIPNetworkDiscovery |
Next, navigate to the following folder for the local account that is used for AIP scanner. Example – C:\Users\AIPScanner\AppData\Local\Microsoft\MSIP
Rename or Delete the MIP folder in that MSIP directory.
(I renamed my folder to mip-old2)
Restart the services you stopped
1 2 3 | Start-Service AIPScanner Start-Service AIPNetworkDiscovery |
You should now see the scanner as Running and Working within the Azure Portal. No more errors should be listed.
Thanks to Angel Marroquin at Microsoft for the assistance on this workaround!

AIP FAQ
With the release of Unified Labeling in Azure and M365, there is now a way to protect your data and label your data appropriately for confidentiality and encryption for your files shares and files on your on premises devices. The following shows how to install the latest AIP_UL client and configure it in Azure to apply those Unified Labeling Policies.
This is a detailed process and I had some issues myself with getting the process simplified. I will do my best here to make this as smoot has possible with as many reference documents that I can input. Always feel free to comment as this data is ever changing and updating as Microsoft updates the offering.
Please refer to this document for a full list of pre-requisites before deploying the scanner:
https://docs.microsoft.com/en-us/azure/information-protection/deploy-aip-scanner-prereqs
For the basics we have the following:
The prerequisites below are still required for successful AIP scanner installation.
1 | Install-Module AzureADPreview |
Before you install the scanner, or upgrade it from an older general availability version, configure or verify your scanner settings in the Azure Information Protection area of the Azure portal.
To configure your scanner:
.
.
to save your changes. to save your changes.Starting in version 2.8.85.0, you can scan your network for risky repositories. Add one or more of the repositories found to a content scan job to scan them for sensitive content.
Note: The network discovery interface is currently in gradual deployment and will be available in all regions by September 15, 2020.
| Prerequisite | Description |
|---|---|
| Install the Network Discovery service | If you’ve recently upgraded your scanner, you may need to still install the Network Discovery service. Run the Install-MIPNetworkDiscovery cmdlet to enable network scan jobs. |
| Azure Information Protection analytics | Make sure that you have Azure Information Protection analytics enabled. In the Azure portal, go to Azure Information Protection > Manage > Configure analytics (Preview). For more information, see Central reporting for Azure Information Protection (public preview). |
.. to save your changes.Tip: If you want to run the same network scan using a different scanner, change the cluster defined in the network scan job. Return to the Network scan jobs pane, and select Assign to cluster to select a different cluster now, or Unassign cluster to make additional changes later.
Repositories found, either by a network scan job, a content scan job, or by user access detected in log files, are aggregated and listed on the Scanner > Repositories repositories icon pane.
If you’ve defined a network scan job and have set it to run at a specific date and time, wait until it’s finished running to check for results. You can also return here after running a content scan job to view updated data.
.
Select Columns to change the table columns displayed.
If your scanner has recently run network scan results, select Refresh to refresh the page. Select one or more repositories listed in the table, and then select Assign Selected Items to assign them to a content scan job. 
In the top-right corner of the unmanaged repositories graph, click the Log Analytics icon to jump to Log Analytics data for these repositories.Repositories where Public access is found to have read or read/write capabilities may have sensitive content that must be secured. If Public access is false, the repository not accessible by the public at all.
Public access to a repository is only reported if you’ve set a weak account in the StandardDomainsUserAccount parameter of the Install-MIPNetworkDiscovery or Set-MIPNetworkDiscovery cmdlets.
Deep dive into your content to scan specific repositories for sensitive content.
You may want to do this only after running a network scan job to analyze the repositories in your network, but can also define your repositories yourself.

You’re now ready to install the scanner with the content scanner job that you’ve created. Continue with Scanner Installation.
Now that we have verified that all prerequisites and configured the AIP in Azure, we can go through the basic scanner install.
1 | Install-AIPScanner -SqlServerInstance "name" -Profile "cluster name" |
If you are not using Azure AD Sync for your Service account, you will need to create a service account in the cloud tenant to use for AIP authentication. If you have synced your on premises service account, you can skip this task.
1 | Connect-AzureAD |
1 2 3 4 5 6 7 8 9 | $PasswordProfile = New-Object -TypeName Microsoft.Open.AzureAD.Model.PasswordProfile $PasswordProfile.ForceChangePasswordNextLogin = $false $Password = Read-Host -assecurestring "Please enter password for cloud service account" $Password = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto([System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($Password)) $PasswordProfile.Password = $Password |

Next, we will configure the App Registration for the Web App that is required to run the Set-AIPAuthentication command that will be used to get the authentication token. We will also assign the necessary Oauth2Permissions for the Web App to have delegated rights to the App.
1 2 3 4 5 6 7 8 9 10 11 | New-AzureADApplication -DisplayName AIPOnBehalfOf -ReplyUrls http://localhost $WebApp = Get-AzureADApplication -Filter "DisplayName eq 'AIPOnBehalfOf'" New-AzureADServicePrincipal -AppId $WebApp.AppId $WebAppKey = New-Guid $Date = Get-Date New-AzureADApplicationPasswordCredential -ObjectId $WebApp.ObjectID -startDate $Date -endDate $Date.AddYears(1) -Value $WebAppKey.Guid -CustomKeyIdentifier "AIPClient" |

In this task, we will use the command created previously to authenticate the AIP Scanner to the AIP Service.
1 2 3 | $pscreds = Get-Credential DOMAIN\scanner Set-AIPAuthentication -AppId "Web App ID" -AppSecret "Password Generated from previous cmd" -DelegatedUser AIPScannerCloud@tenant.onmicrosoft.com -TenantId "Your M365 Tenant ID" -OnBehalfOf $pscreds |
Successful OUTPUT:
Acquired application access token on behalf of DOMAIN\scanner
1 | Restart-Service AIPScanner |
Look to these reference documents for further details:
Set-AIPAuthentication
Get Azure AD Token for the AIP Scanner
The default settings configure the scanner to run once, and in reporting-only mode.
To change these settings, edit the content scan job:
1 | Start-AIPScan |
The scanner is now scheduled to run continuously. When the scanner works its way through all configured files, it automatically starts a new cycle so that any new and changed files are discovered.

Microsoft has put out a new standard for security defaults in a tenant that harden default settings in the org. Security defaults make it easier to help protect your organization from these attacks with preconfigured security settings:
Now, there might be many reasons why you would not want these defaults enabled in your tenant, just remember that you will need to setup these things manually should you change the security defaults setting.
This should set the defaults for your O365 tenant as you wish to have them. Please refer to the references below for more information and detail into each of the security defaults.

I have a VM that is joined to my Azure AD test tenant domain. I was having issues using RDP to access the box with my Azure AD credentials (username@tenant.onmicrosoft.com). I kept getting the following when trying to connect:
So I started researching and found that this was an common issue that many have started to face with their Azure AD Joined machines. Unfortunately, at this time it isn’t quite as easy as “open up a new RDP connection, type in the computer, type my email, and connect”. Here are the steps to connect a session to that Azure AD joined computer.
First, open remote desktop as if you were going to connect to any other computer. Type in the computer name or IP address and expand the the Show Options section. Next, click the Save As button to save the RDP file to your computer. At this point you can close the Remote Desktop Connection window as it isn’t needed any longer.
Next, open Notepad. Click File -> Open -> location your RDP file that was saved in the previous step.
Go to the very bottom of the list of parameters and add the following two lines:
enablecredsspsupport:i:0
authentication level:i:2
Save the changes to the .rdp file
NOTE: You can also add your username that will be used to connect to the session in the file as well:
username:s:.\AzureAD\YOURusername@YOURtenantname.onmicrosoft.com
Now you are ready to connect! Double click on the RDP file and connect to the Azure AD Joined computer.

As many of you know I have an existing Azure/M365 Tenant that I use with my company as many of you all do as well. When you get an MCT Certification, you get access to a monthly credit in Azure.
So I clicked on Activate and when activating the subscription, it created a new Azure tenant that was linked to my MCP ID and not my LDLNET ID. The problem here was that my Microsoft Identity was a different email address (@live.com) from my tenant Microsoft Identity (@ldlnet.net).
So now I have a new tenant that I really don’t need, so I started thinking, could I transfer the subscription to my LDLNET tenant and keep the monthly credit. The answer is Yes AND No.
First, I created a guest account in my LDLNET tenant for the @live.com email address and then temporarily gave the account Global Admin privileges. This was so that I could access the subscription when transferred and assure that the proper accounts that needed subsequent access to the subscription get what the owner permissions by logging on with the @live.com account in the LDLNET tenant. I then activate the account in LDLNET.
NOTE: This is probably NOT the most secure option to start, but I will update as I find the article’s that define least privilege for setting this up. I’ve seen a couple of articles, but it wasn’t the exact same way. The thing here is that the billing cannot be transferred since it is being handled by Microsoft Directly with the credits. So, I have to keep the @live.com account active in the LDLNET tenant so that it bills correctly.
Next, I go to the setup tenant and look at the subscription Overview:
At the top of the screen, I choose Change Directory. Since my @Live.com account was an admin for the LDLNET Directory now, I could choose the directory on the following screen:
NOTE: I couldn’t change the billing on the setup tenant nor transfer it since it was through Microsoft, but why would I want to anyway since it’s my credit that was given to me monthly. Also, on my visual studio subscription, I made sure that my @ldlnet.net address was an alternate access account on the subscription. I want to make sure the credit stays after this month!!
So, I received the email asking to accept the transfer and clicked Accept The Transfer:
Once the subscription was accepted and transferred to LDLNET, I logged into LDLNET tenant with my @Live.com account. I then went to the subscription and made sure to add all necessary accounts to the subscription so that they would get access:
Once completed, I logged in with my Original Global Admin account and changed the @Live.com account permissions to a Global Reader in my LDLNET tenant, then gave them Owner Access permissions to the Subscription specifically.
And that has completed the transfer. Hopefully, the subscription will continue with the monthly credit as per my MCT Certification allows. I will update if something changes. If you have a better way to do this, please comment and I will be happy to verify it and post!
I have been working on updating my skillset to M365 and passed the final exam today to achieve it. I am hoping that the certification will assist me with attaining work moving forward.

I recently setup a backend RDP server so that I could test our remote services. I went through the installation process and installed my RDP license on the server successfully. The problem was that I was not getting an error when logging onto the server locally to check the status of the RDP Server:
I also had Events within Event Viewer:
Log Name: System
Source: Microsoft-Windows-TerminalServices-Licensing
Date: 6/24/2020 3:44:16 PM
Event ID: 18
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: SRV2016-02.ldlnet.net
Description:
The Remote Desktop license server “SRV2016-02” has not been activated and therefore will only issue temporary licenses. To issue permanent licenses, the Remote Desktop license server must be activated.
Usually, this error appears as a notification popup in the bottom right-hand corner of the screen saying:
Remote Desktop licensing mode is not configured
Remote Desktop Services will stop working in xx days. On the RD Connection Broker server, use Server Manager to specify the Remote Desktop licensing mode and the license server.
And when you click on this notification popup, it doesn’t redirect you anywhere and it gets simply disappeared which is a quite frustrating situation.
I thought I had this set properly, but the RDP Licensing Diagnoser application told me that I needed to choose the licensing configuration to distribute for Per Device OR Per User. The licenses I installed were per device so I did some research.
I found out that this had to be configured via the Registry, PowerShell, or could be configured through GPO. I chose to do GPO since that would always apply on my servers in my domain.
Here’s how to change the licensing mode for Remote Desktop session host using the registry editor and get rid of the error message Remote Desktop Services will stop working in xx days:
At first, press Windows + R keys together and then type regedit in the Run dialog box and press Enter key.
Next, in the left pane of the Registry Editor, navigate to the following registry key:
1 | HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\Licensing Core |
Next in the right pane, double-click on the LicensingMode to edit its value and then change the Value data according to your requirement:
Set the Value data 2 for Per Device RDS licensing mode
Set the Value data 4 for Per User RDS licensing mode
Finally, click on the OK button to save the changes.
Now, restart your computer and check if the Remote Desktop licensing mode is not configured issue on Windows Server has been resolved or not.
Once you changed the licensing mode, now everything will be reported accurately and the Remote Desktop session host will recognize the licensing configuration.
First Logon to a machines that has Group Policy Tools Installed, press Windows + R keys together, type gpedit.msc, and press Enter key.
Within Group Policy Editor, create a new GPO and link it to the level that you need to link it to. (In my case, the domain level.) Navigate to:
Computer Configuration > Policies > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing.
Next, double-click on the “Use the specified Remote Desktop license servers” setting and then select Enabled option. Finally, enter the names of the license servers (host name or IP address) and then click on the OK button.
Similarly, double-click on the “Set the Remote Desktop licensing mode” setting and then select Enabled option. Finally, set the licensing mode (Per Device or Per User) and then click on the OK button.
Once all these changes are done, close Group Policy Editor, go to the RDP Licensing Server and run a gpupdate /force to refresh Group Policy.
Now, when you open the Remote Desktop Licensing Diagnoser, you shouldn’t see any errors like the remote desktop licensing mode is not configured on windows server or any kind of issues regarding your licenses.
You can also use PowerShell to set the Licensing Mode via the Set-RDLicenseConfiguration cmdlet from the RemoteDesktop PowerShell Module which is installed with Remote Desktop Services:
1 2 3 | Imort-Module remotedesktop Set-RDLicenseConfiguration -LicenseServer @("srv2016-01.ldlnet.net","srv2016-02.ldlnet.net") -Mode PerDevice -ConnectionBroker "srv2016-01.ldlnet.net" |

Microsoft365 allows the tenant administrators to grant external users access to content in their tenant by setting them up as a guest in their M365 Tenant. Microsoft365 provides a guest access feature that you can use to grant content access to contractors, partners or others who need access to certain content.
However, the process of setting up a guest user works differently from that of setting up a normal, licensed user from within your organization.
By default, Microsoft365 Admin Center contains a Guest Users screen. You will also notice, however, that this screen does not contain an option to create a guest user. In fact, the only things that you can do are search for a user or delete a user.
Being that the Guest Users screen doesn’t give you a way to create a guest user, you will need to either delve into PowerShell or perform the task within Azure Active Directory. I prefer using PowerShell, and will write a post about how to perform this via PowerShell, but unless you need to create a large number of guest users, it is usually going to be easier to use the GUI. Below is how to create a guest user via Azure AD.
To create a guest user, expand the Admin Centers container and then click on Azure Active Directory. When the Azure Active Directory Admin Center opens, click on the Users container. You can see that just to the right of the New User option, there is an option to create a New Guest User.
NOTE: Creating a guest user account isn’t like creating a normal user account. Rather than providing the account details and clicking a Create button, you will instead need to send an invitation to the user.
Make Sure You Verify Their E-Mail Address Beforehand!!!
Choose Invite User > Enter the Identity Information
Next Enter A Personal Message (optional) > Choose their Group Membership > Update any AAD or M365 Permissions under Roles > Update their Sign In Settings > Click Invite to send the invitation
After a few minutes, the specified user will receive an e-mail invitation that looks something like the one shown below. The recipient will need to click the Accept Invitation button and accept the terms of use.
When the guest user completes the registration process, they are logged into Microsoft365 however, there are no applications initially available to the user. This is because unlike a standard user, external users do not automatically get access to applications.
If you go back to the Guest Users screen, you will see the newly created guest user listed (you may have to refresh the screen). As previously noted, you can’t do much from this screen. You can, however, click on the user to see a few extra details now. Example is below.
The way that you grant an external user access to data is to add the user to a group that has access to the data. Let’s suppose, for example, that for whatever reason, you need to add an external user to a Teams Group named Microsoft Exchange Guys. To do so, you would go to the Groups folder within the Microsoft 365 Admin Center, click on the Microsoft Exchange Guys group, and then edit the Membership list, as shown below.
After clicking the Edit button, click on Add Members and then select the external user that you wish to add. Click Save to complete the process,
If you now go back to the Group’s membership, you are able to see the Microsoft Exchange Guys group membership showing the new guest user as a member.
Granting access in this way does not provide the external user with blanket access to the Teams Group. However, another group member is now able to e-mail the external user a link to the Teams Group. The external user can use this link to access the Group within the Teams app.
NOTE: Keep in mind that I am only using the Teams Group as an example. You can use somewhat similar techniques to provide access to a variety of Microsoft365 AND Azure AD content.

How To Enable Guest Access for Office 365
In my environment, I have a Windows Server (2019) Core edition server installed with Exchange 2019. Most of the time, I have to get on the server to run PowerShell commands for maintenance purposes, etc…
Well, by default, Windows Server Core opens the command prompt when you logon and then I have to manually open PowerShell from there to run cmdlets, etc…
However, if you would like to change the default cmd to PowerShell, you can change it by changing the Registry value.
The Registry that I’m talking is located under the following location:
1 | HKLM:\Software\Microsoft\Windows NT\CurrentVersion\WinLogon |
The easiest way I see to change the value is to use the Set-ItemProperty cmdlet within PowerShell.
Open Windows PowerShell within Server Core command prompt. You can type “PowerShell” on your command prompt.
Then, enter the following command on PowerShell console and hit enter:
1 | Set-ItemProperty -Path 'HKLM:\Software\Microsoft\Windows NT\CurrentVersion\WinLogon' -Name Shell -Value 'PowerShell.exe' |
Once completed, you will need to reboot the computer from PowerShell:
1 | Restart-Computer -force |
When the computer has rebooted and you have logged on, PowerShell should load by default instead of Command Prompt.
Now, since I have an Exchange Server installed on this server, there is a Command in the $bin directory called LaunchEMS.cmd that will load the Exchange Management Shell for you. So instead of loading just PowerShell, I tell WinLogon to load Exchange Management Shell so that I do not have to do any additional typing or searching for EMS on the box. Remember, Server Core has no GUI!
I run the same commands as above, but just change the value to LaunchEMS.cmd
1 | Set-ItemProperty -Path 'HKLM:\Software\Microsoft\Windows NT\CurrentVersion\WinLogon' -Name Shell -Value 'LaunchEMS.cmd' |
Then Restart the Computer:
1 | Restart-Computer -force |
Once Rebooted, you can logon and EMS will be the only window prompt that loads in the shell!
NOTE: You can always run cmd from the prompt to open Command Prompt and also run PowerShell.exe to open regular PowerShell from the EMS Session Window.

As many of you that follow Exchange have knowledge of, Microsoft releases their updates for Exchange Server every 3 months. Below is the latest update for Exchange Server 2016. I do not run 2016 any longer in my lab, but please post if you have issues with the installation and I can investigate!
Cumulative Update 17 for Microsoft Exchange Server 2016 was released on June 16, 2020.

In my experience with doing Exchange migrations to the cloud, there always seemed to be an issue with EWS throttling causing very slow mailbox moves. The remediation to this was to always contact Microsoft EXO Support and open a ticket to request that your EWS throttling for your tenant be lifted so you could move your mailboxes more quickly.
The reason for the EWS Throttling was to keep large amounts of data from flooding the front end server farm possibly causing a temporary outage or corruption of data going to the cloud since there are literally thousands of customers going through the same server farm and possibly migrations. Throttling was a way to keep everything in check.
Microsoft recently made an interesting change to the automated support handling capabilities of the Microsoft 365 admin center to handle requests for Exchange Web Services (EWS) throttling to be lifted for up to 90 days without human intervention.
Once the setting is changed in the tenant, it will be effective after about 15 minutes for replication to the server farm. You should then be able to run your migrations at full speed.
NOTE: Changing this setting is only effective for EWS migrations and NOT IMAP Migrations (such as from G-Mail).
Having this option online in the portal saves a tremendous amount of time when working to get your Exchange migrations to the cloud completed. Hopefully there will be more to come. I just hope it doesn’t keep me out of a job!
