Changing UPN AD User Domain
I changed one of our users UPN domain name in AD from domain.local to domain.com. This change then synced the user's AD account into O365 as it should. I then realised that I had picked the wrong UPN...
DirSync sometimes fails to pick up the UPN changes. You can however change it directly in O365 via the Set-MsolUserPrincipalName cmdlet.
Quick follow up from my end, I checked and our is involving first.last@somewhere.com where the first.last changes. We have to disable csuser and re-enable it which fixes the issue for us. Sounds like this is a different issue, but wanted to see if I could help with anything.
