Thus far, nothing has resolved this issue.
As the install was Office 365;
Deleted OST file
Deleted User Mail profile
Un-installed Office 365
Cleared application / user folders - rebooted
Installed Office 2016
The only other thing i can think of is;Backup user data, wipe the drive (2 min max as it is a nvm drive) Image and restore user data.
This is an odd issue to say the least. I am hoping the o365 team can determine a solution rather than having to go that route.
I feel like you're shooting a shotgun in the woods during a new moon and praying to hit a target.
If you don't have permission to make any changes because of GPO and you have no visibility in office 365. Then just escalate the issue. Otherwise it's just a time waste for all involved.
Lol- I did. The O365 team kicked to the IR Team ( incident response), who closed it as I was working ...
Guess I’ll just have to reimage it ,.,.,
