All of a sudden, a OneDrive dialog box appeared on my desktop telling me that it failed to login with my Hotmail account. I tried logging in again but it showed the same message that it couldn't login. I tried to login on https://hotmail.com, and it shows my account does not exist. After many attempts, it shows "Connection Error" and goes back to the login page without any error message. It is not my connection issue because it happened on multiple devices. It has happened to my secondary account as well.
Is Microsoft being hacked right now?
