How to fix Outlook – Error code CAA2000B – AADSTS500011

Outlook – Error code CAA2000B – AADSTS500011
Hi All,

One of our employees has been getting the following error since a couple of months. He can still use outlook by skipping the login screen at starting.

I’ve tried the following solution without success:

Select FILE, ACCOUNT SETTINGS, from the drop down, ACCOUNT SETTINGS, when the account settings box opens you will see the email tab is the default and the users name is listed. Double click the users name and the Exchange Account Settings dialog box open, UNCHECK the box (Use Cached Exchange Mode to download email to an Outlook data file) Close everything and restart the PC

Kind regards,

Select FILE, ACCOUNT SETTINGS, from the drop down, ACCOUNT SETTINGS, when the account settings box opens you will see the email tab is the default and the users name is listed. Double click the users name and the Exchange Account Settings dialog box open, UNCHECK the box (Use Cached Exchange Mode to download email to an Outlook data file) Close everything and restart the PC and it should stop the issue. I did mine and left it open all night and it never came back again.
