Anurag1311&nbsp;no. Teams recognizes users using the GUID that Azure AD generates per user, no issue if you change the email address. To note it may take longer than you expect for the new address to show inside Teams, everything will work it just caches some of that data for a long time, I've seen it take a week.

Anurag1311&nbsp;Typically* they will log in using their UPN, this isn't necessarily the same as their email address. If you change the email but not the URN they will still log in using UPN. If you change both there may be some AD replication time but Teams will remain associated with that user.

* typically because there are configs to use email as an alternative to UPN.
