Outlook M365 – Need Password dialogue disappears quickly

You are using Microsoft 365 and you turn on your PC and open Outlook but discover that Outlook requires a password. The message “Need Password” is staring at you from the info bar at the bottom of the Outlook window. You click to try and input your password, but it quickly pops up then the password dialogue box disappears. There are few suggestions with a few different Methods and workarounds. In short, what worked for me was as follows:

  • Close all M365 Application (Outlook, Word, Excel etc.)
  • Add a DWORD called DisableADALatopWAMOverride with a value of 1 under the registry HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\
  • Open Word – Sign-in

Start Outlook and the problem should be fixed.
