Office 365 - Outlook 365 sign in window disappears unable to login
Had an issue today in outlook where the sign-in window to add the credentials kept on disappearing, little bit annoying for the user as no emails were coming through. Tracked it down to a registry change, once this was added the login box popped up as normal. Go to the registry editor (Win+R; regedit) go to HKEY_CURRENT_USER -> Software -> Microsoft ->Office -> 16.0 ->Common -> Identity Inside "Identity", create a new REG_DWORD value called "EnableADAL" and leave the value at 0 the login window is slightly different but it works :) Buy me a beer :)
