I have a couple users whose Office 365 is asking them to Sign In. After putting in their Microsoft account name (email@example.com), however, the password screen is solid white.
I have tried the DisableADALatopWAMOverride = 1 registry entry found [here](https://office365.uservoice.com/forums/264636-general/suggestions/32694751-outlook-is-not-syncing-and-giving-a-need-password?page=1&per_page=20), but that does not fix the problem.
Any help would be appreciated.
Edit:. To clarify, they are trying to log in when prompted after opening Word or Excel.
