Once (KB5018410) is installed in Windows 10 Outlook 2019 version 16.0.10390.20024 or Outlook 2016 constantly asking for a mailbox password regardless if password is saved.
Once this update was removed and the system restarted the problem went away.
Unfortunately, KB5020435 has not resolved that issue.
Mail server: Exchange 2010.

Exact same Problem here with KB5018410 and again with KB5019959. No clue whats the cause of these Outlook Problems.
Also users can't access shared calendar from other users.
