I first noticed the issue about 3 years ago (and there are plenty of posts on this issue going back that far) when I was using the Android email app.

Clicking OK then requires you to re-input your credentials. Afterwards when opening the email app you're suddenly greeted with " please sign into (username in place of actual account name). What happens I setup an email account on my Samsung Galaxy Note 9 android device (whether the native android app, or Outlook) using the auto account feature, everything works for about a week or two. The issue for whatever reason and no matter the email app (Android or Outlook) continuously drops email credentials after about a week or two.
