Microsoft Teams and Outlook login not working? Recent Windows 10 update could be to blame

Microsoft said it was a “small percentage” of users that have been impacted by the problem. Of course, if you’re in that percentage – no matter how small it is – it’s likely to be incredibly annoying.

Thankfully, if you’re being hit with this issue there is a simple workaround that Microsoft said may fix it. In a post on the admin portal, Microsoft explained that restarting your device should resolve the login issue.

Failing that, Windows 10 users can use the web versions for Teams, OneDrive for Business or Outlook.

Mobile and non-Windows versions of the apps aren’t affected either.
