Hi AshJor
>Do we have to just turn off the last physical server and not uninstall exchange server 2019 ?
Yes exactly

>Any gotchas or issues managing recipients via the new Exchange Management Tools post-decommission?
Make sure, your other systems (IAM, Automation, Ticketing Tool, etc) are able to work with the Recipient Management. You can't use a Remote PowerShell to connect to Exchange anymore. You need to be able load the Commandlets
Kind Regards

One of the details is that after turning off the last Exchange server and before running the Active Directory Cleanup script, the recipient management command will still try to connect to the Exchange server for admin audit logging, resulting in an about 40 second delay for the command execution.
