Can't connect on-premise users to exisiting Office 365 users
Hi Guys,
We've recently taken over the IT support of a customer from another IT company. They had Office 365 synced to their on-premise DC of the previous IT company. The directory sync has been stopped and AD Connect removed from the previous DC. The Office 365 accounts now show as 'Cloud'.
I have configured Azure AD Connect on our DC and ran through the setup, which I believe to be correct, however I just can't get the on-premise accounts to connect with the existing O365 accounts. I get the following error "AttributeValueMustBeUnique". I have verified that the UPN's match as does the primary SMTP but the issue remains. Any new accounts created in the on-premise AD sync without issue.
Kind Regards,
James

Thank you very much Chris, that seems to have done it!
- Cool glad it worked! Funny I was just looking this up to do it myself last night and caught your post and remembered that step so figured it might be it 🙂
