Hi I am performing a migration of mailboxes from Exchange 2007 to Office 365 following the staged migration method.
The majority of mailboxes have migrated successfully however I have a small few that are reporting the following error:
"need to have an owner before trying to create the proxy"
How do I resolve the error?
I have ADFS and dirsync setup for SSO. Dirsync is not reporting any issues with the accounts in question and is actively syncing the accounts.
Regards,
Aaron.
