Query Regarding Changing UPN and Email Address with new Domain Name in Exchange Hybrid Environment
Hi Microsoft Tech Community, I'm currently navigating a transition within my organization where we need to change the UPN and Email Address while retaining the old email address as a secondary ad...
Hi janakkhadka,
we recently changed the UPN for our users in the same environment, and we had no problems what so ever with Outlook profiles, passwords and Microsoft Teams.
The only problem we had was the OneDrive shared documents, but were prepared for this.

What was the case for Outlook Profile after changing the Domain of the Users' UPN/Email?
