Have exchange hybrid environment, and I have on-prem and online mailboxes.
I've created distribution group at on-prom side. I've assigned online (synced from on-prem) and on-prom mailusers as owner for this group. This users granted access to manage recipients for this group (via adding new role).
Then I've opened outlook for one of this on-prem user and tried to add and remove recipients for this distribution group. This was successful.
But then I trading to do the same in owa by online users I got error, something like "this is on-prem group and you should manage it from on-prem environment".
My question is: is it possible to create distribution list (online or on-prem - no matter) that can be managed by both online and on-prem mailusers? If yes, then how can I achieve this?
