Q: Before migrating to office 365, I can add second owner to a distribution in Exchange admin. But I can’t do it after we migrated our Exchange to office 365.

chicagotech.net: Assuming you still manage Active Directory on your site, you don’t have option to add group owner in AD and you will get an error if you try it on Office 365 Exchange admin center.
