Constantly being asked to reauthenticate accounts in Outlook for Mac

Hey everyone,

I started running into a strange issue a few days ago. I am using Outlook for Mac Version 16.102.1 (25101829) with seven accounts configured.

Out of nowhere, I keep getting repeated prompts to reauthenticate all my accounts. I use the Microsoft Authenticator app on my iPhone, get the push notification, approve the two digit code, and everything goes through fine. A few hours later, Outlook shows the same pop up again asking me to reauthenticate.

I have gone through this process at least ten times now, and it keeps happening.

Is anyone else seeing this issue or found a fix?
