Any update? My staff and I are having the same problem, and we're super stressed. Worse yet, I deleted the email address from the iOS Mail app to see if reinstalling it would solve the problem, and now it's not letting me add it back in.
I had the account on the iPhone for years. It stopped working yesterday. It is asking me to re-enter the password. However, it does not accept it. I am able to log in on my desktop and online with no issues.
Today, I am unable even to use the Teams app on my iPhone to connect to a meeting.

Our investigation into the authentication failures has so far revealed that there is an issue with the authentication tokens being sent from the iOS native mail app. We're continuing to investigate and determine the next steps to troubleshoot the issue.
