When an on-premises distribution group is synced to a Microsoft Office 365 organization through Active Directory synchronization, migrated users who are owners of the distribution group can't manage it in Microsoft Exchange Online. For example, a user may receive an error message that resembles the following:
The action '<cmdlet>', '<property>', can't be performed on the object '<name>' because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization
Distribution groups that are created in Office 365 through directory synchronization must be managed in the on-premises environment. Distribution group owners must manage the group by using on-premises tools for Exchange Server such as the following:

However, this owner can't manage the distribution group because the access control list (ACL) for the group doesn't grant permissions to the owner.
Additional tools for managing distribution groupsThere are additional on-premises tools that can be used to modify group membership.
