End User OWA and Office 365 Suite Credentials Inconsistent
Well I attempted to change the UPN and change it back and still no dice. It still works the exact same.
Another issue seems to be happening as well. Outlook won't remember her credentials now at all either. They get cached in the credential manager but outlook will still promt for them (These are the credentials that should be wrong but she has to use to log in. The FristInitialLastName@domain.com credentials). Also whenever she switches networks and opens outlook for the first time after the switch it won't accept either of the credentials at all and continuously prompt for the password.
Again, everything works fine on the OWA and Mobile App. We also attempted it briefly on Thunderbird to similar issues with only accepting the FristInitialLastName@domain.com UPN. Although it did not ask for credentials repeatedly. Outlook is causing the most issues. And yes Outlook and the PC are up to date, and we were able to recreate this issue on 3 computers.
At this point I am wondering if it is some sort of corruption with the AD account or the email.
I solved the issue. For anyone who is reading this and is experiencing similar problems. I ended up having to change the UPN back, waiting a few days, and trying again TWICE in order for it to work.
Very odd issue. I guess 3rd time is the charm.
It could be a corruption as well, yes.
I would consider to open a support case for that issue. Microsoft can help to identify the problem.
