Hello. First the background to my issue:
We had a user resign so I disabled her account in AD. When her replacement arrived, I went through the AD rename process for the new user. Big mistake, apparently, as it caused major malfunctions with the new user. So, I deleted the account altogether and created the new user's account from scratch. After doing so, I received this error on sync:
User already synced or not updated:
jane.doe@domain.local (69279995-90c1-4cd6-9578-0d1c1b2872b3) => jane.doe@domain.org
Reason: UPN jane.doe@domain.org conflict detected
I thought this was being caused by what appeared to be an orphaned user in Office 365 for the old user account. I removed the orphaned user with AD Azure Powershell, but this doesn't seem to have helped. I've deleted and recreated the new user's account in AD and the provisioning process doesn't even appear to pick it up anymore.
I'm totally at a loss for ideas. Thanks.
