I have a mail distribution group in on-premise Exchange server: DG-AdminTi
That email is managed by a mail enabled universal security group: SU-AdminTi
Both accounts are synced to O365 by AD Connect.
The problem is when check the OWNERS of DG-AdminTi in O365, I don't see SU-AdminTi
If I change the ManagedBy of DG-AdminTi by a user which his mailbox is migrated it works.
It looks like ManagedBy info is not replicated in O365 for On-Premise mail enabled security group. Why is that?
