Dave Pool's solution worked for me. Thanks for reposting it Anonymous user
here it is again...
Dave Poole's solution did it for me, others didn't (sort this out Microsoft). His method is below since his comment is starting to get buried below the thanks to him!
"I found an unconventional fix to this:
1. Whilst MS Teams is open, right click in System Tray and hit sign out.
2. You will then be taken to a login page with your email address autofilled. Deliberately enter an INCORRECT email address (.ukk or .comm) and hit sign in.
3. You should then be taken to a different login window, where you have the opportunity to re enter your email, which should then take you to a password window where you can complete your new credentials.
It's weird, simply clicking sign in when my email address was autofilled kept me in the loop, but entering the wrong one worked. I also went through some of the other suggested steps like clearing my generic credentials- so it's possible you may have to do that as well. "
