We have a client that would like to switch his UPN Suffix for all his Users, Distribution Groups, Shared Mailbox and Teams. I have done this long time ago for the users and never run into a problem. Just curious has anything changed or has anyone run into any issues. If i am not mistaken we can run a script to change the suffix for all the users and then another script to added the new suffix as the Proxy address main and then the old one as an alias.
Has anyone changed the Teams and run into any problems? If so is it done by powershell?
