I have a new user account that was created a few days ago. Today I started setting up their workstation, but I'm unable to connect Outlook to Office 365.
I created a new profile, autodiscover works, but then I am continually asked for a password. I know the password is correct because I can login to OWA with no issues.
I tested this on several workstations and the outcome is the same. I can setup other users fine, so it seems limited to this one user account.
