All,
I made a pretty big screw up and need some help getting out of a jam. Here's what we had
Office 365 account with an Azure domain. We had a verified domain we'll call it "website". So all my users in Office 365 had a username of first.last@website.com. With an exchange license assigned.
I was starting to test syncing to our on-prem Active Directory. I was making some changes and ended up syncing the entire on prem AD before it was ready. Luckily the fallout wasn't horrible. Everything seemed to work but all the O365 usernames changed to firstlast@ad.website.com (my AD forest)
So now while everything still works... I have all kinds of junk (security groups etc) inside my O365 portal and I am having to manually change the user name and password on all outlook clients because it is failing to authenticate.
All of that said... is there any...
