Hey guys, not sure if anyone else is continuing to have issues with this. As luck will have it, we ran into this same issue and noticed the password prompt would "flash" and immediately disappear as well for Outlook.

Read through this thread and disabling MFA is definitely NOT an option I would entertain.

I noticed End User was not logged into OneDrive... logged user into OneDrive and was immediately prompted afterwards for credentials which resolved the issue with Outlook.

I am waiting to see if we run into this issue again to test it again but just thought I would put this out there in case it is able to help someone.

We had this exact same problem for about 3 users. (out of thousands) and we do not have onedrive enabled for our users nor do we use Hybrid Domain join.

Any other ideas? other than disabling MFA support? in fact is that all that EnableADAL 0 does ? Is disable MFA support for Office Apps?

Thanks,

Robert
