While working in Outlook 2021 for the desktop (also affects older versions), sometimes Outlook will show “Needs Password” in the bottom right status bar.  If you click on the text, a window will appear and almost immediately disappear.  

One fix for this issue is clearing the outlook credentials in Windows Credential Manager.

An easier fix that I have found is to refresh DNS. 

  1. Close Outlook
  2. Open a command prompt
  3. Type these two commands in this order:
    • ipconfig /release
    • ipconfig /renew
  4. Open Outlook

I have yet to find a permanent fix for this issue as it continues to reappear on multiple accounts on multiple computers.  It tends to happen the most with work/school accounts.

Hope this helps you out.  It has been very frustrating for me.  So glad I found the simple release/renew fix for it!
