I have a user that keeps getting prompted for MFA - from Desktop MS Teams. I've revoke re issued tokens, reset session and still get its every morning. This morning I ran across that he has two accounts setup under email & accounts - Accounts used by other apps.
Could this cause MFA for MS Team Desktop? I so, with one account being work (requiring MFA) and one account being personal (has MFA setup on it). How can I get them to co-exist?
Read too fast. Didn't see it was hybrid (thought it was a personal device AAD registered). What about the logs? What are they telling you about the MFA prompts? You can have more than one account, and mixed, under the Windows 10 settings.
