Greetings. We removed Exchange 2010 a while ago and moved to Office 365. Exchange was completely uninstalled and the physical server was decommissioned.
I know that some AD attributes remain in the schema from Exchange, which I'm guessing is not a problem.
Question - can I safely remove the following Security Groups from the Users ou ?
- Exchange Domain Servers
- Exchange Enterprise Servers
- Exchange Services
- Exchange Operators
- ExMerge Operators
I don't see any reason why we need these, since there is no on-premise Exchange server any more. All user management for mail is done in the Office 365 management console (or through Powershell).
