Outlook on Office 365 Need password login prompt disappears

Today I had an issue with a user using Outlook on Office 365 where Outlook says “Need password” on the bottom right hand corner however when you click it the login prompt does not appear.

I tried closing Outlook and re-opening to find the username/password box flashes and disappears quickly.

Solution 1:

  1. Open Start button -> Settings -> Accounts -> Access work or school.
  2. Click disconnect
  3. Close and re-open Outlook.

Solution 2:

  1. Close down Outlook
  2. Add a DWORD named DisableADALatopWAMOverride with a value of 1 to the registry in this path:
  3. HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\
  4. Open Outlook and try now. If this doesn’t help try restart.

In my experience I tried solution 1 and the problem came back again. I have tried solution 2 and it immediately started working (without a restart).

Fixed 🙂
