Installing Exchange Management Tools in Different Site Than Exchange Server and FSMO
Hello,
We have one Exchange 2016 server, which is only used for Recipient Management and successfully navigated the following article to install the Recipient Management Tools on a non-Exchange server in the same site as our Exchange 2016 server and AD FSMO (The server authenticates to FSMO).

We'd like to install the Recipient Management tools on machines located in a different AD site from Exchange 2016, which do not authenticate to a FSMO domain controller. However, we receive the error "Active Directory doesn't exist or can't be contacted [CannotAccessAD]" during installation.
The two prevailing theories I've found are we need to follow the steps in "Prepare Active Directory and domains for Exchange Server", which I thought was already completed in step 3 of the above article, when installing the Recipient Management Tools from Exchange 2019 CU12 ISO.

The second is we're installing the tools on an endpoint that is in a different site than FSMO and therefor the endpoint is authenticating to a DC without that role. If that is the case, has anyone done this and do we simply move FSMO to the DC we're authenticating against, run the installer and when the install completes, move it back?
If neither of those cases are correct, does anyone have any ideas? Thanks for your help.
- Try installing from the command line and specifying the appropriate domain controller using the "/DomainController:" switch

That did not work; we received the following error:
Setup can't use the domain controller '[redacted1]' because it belongs to Active Directory site '[redacted2]'. Setup must use a domain controller in the same site as this computer
BUT this lead us down the path to resolve the issue by identifying a conflict in AD Sites and Services. Once this conflict was fixed by properly mapping our subnets, we were able to install the Management Tools.
Thank you!
