Unable to edit Group membership of Distribution list using Outlook in Exchange Hybrid Environment.

raj a 316 Reputation points


We have a Hybrid Exchange Environment where all our mailboxes are already migrated to Exchange Online. Distribution lists are created in the Exchange On-premises environment and then synced to Azure.

We are encountering an issue where we are unable to edit DL group membership using Microsoft Outlook.

The user is having the owner\read-write member permission on the DL.

What could be the reason for this?

    Thats expected since the group itself is homed on-prem.

    You will need to manage on prem or delete the group and recreate the group in 365 so it can be managed there.
