Can’t sign in to Outlook

If your Outlook is continually prompting you for a password to sign in please follow these steps.

1. Open the Regedit application as the user. (This should not be done as the administrator as it will apply the changes to your profile instead of the user’s settings.)
2. Go to “Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity”
3. Verify if there is a DWORD value named “EnableADAL” that is set to 0. (If “EnableADAL” is not found in the registry, create a new DWORD and name it “EnableADAL”.)
4. Update the DWORD value for “EnableADAL” to 1.
5. Select OK.
6. Verify if there is a DWORD value named “DisableADALatopWAMOverride” that is set to 1. If “DisableADALatopWAMOverride” is not found in the registry, create a new DWORD and name it “DisableADALatopWAMOverride”)
7. Update the DWORD value for “DisableADALatopWAMOverride” to 0.
8. Select OK.
9. Close Regedit.
10. Open Outlook and sign-in.

The DWORDs should look like the below screenshot, where EnableADAL’s Value data is set to 1 and DisableADALatopWAMOverride is set to 0
