Exchange Server 2016 or Exchange 2019 Setup has detected that the target computer is an Active Directory ___domain controller, and we don't recommend installing Exchange on ___domain controllers.
If you install Exchange on a ___domain controller, be aware of the following issues:
Configuring Exchange for Active Directory split permissions isn't supported. For more information about split permissions, see Understanding split permissions.
The Exchange Trusted Subsystem universal security group (USG) is added to the Domain Admins group. This action grants all Exchange servers ___domain administrator rights in the ___domain.
Exchange Server and Active Directory are both resource-intensive applications. There are performance implications when both applications are running on the same computer.
The ___domain controller must be a global catalog server, but Exchange services might not start correctly on a global catalog server.
System shutdown will take considerably longer if Exchange you didn't stop the Exchange services before you shut down or restart the server.
Demoting the ___domain controller to a member server isn't supported.
Running Exchange on a clustered node that's also an Active Directory ___domain controller isn't supported.
Therefore, we recommend that you install Exchange on a member server, not on a ___domain controller.
