Why a different username format?
For future reference you can check sync conflicts (with instructions to correct them) from the Azure AD Connect Health -> Sync Errors blade in de Azure AD portal.
Thanks very much for your reply.
You're exactly right about the conflict. I had overlooked a contact we had created for this user so that users whose mailboxes were migrated to the cloud would be able to send mail to this person's regular Exchange (on prem) mailbox. (Since he had a account created directly in Azure, we left him in an unsynchronized OU, which meant that his name in the O365 GAL pointed to the mailbox associated with the Azure account's mailbox in Exchange Online.)
I'll have to delete that contact. Would the most straightforward thing be to move him back to an unsyncronized OU in AD and let that new account be removed from AzureAD, then move the AD account back to a synchronized OU so that it would be recreated? Or would it be better to modify the existing Azure account? If the latter, what would I change in AD in order to change the account name in Azure since I can't make that change directly in Azure?
Thank you again for your help.
- That would be one way. Alternatively you can delete the user from Azure AD. It will then first be soft deleted and you will need to do a hard sleet after that to remove the user completely from Azure AD. Then trigger the on prem account to be synced again.
