In the role of a Distribution Group owner on a Microsoft Exchange Server 2010 server, you try to remove members from a distribution list that you own. When you try to remove some of these members in Office Outlook by using the Distribution List Membership tool, you receive the following error message:
Changes to the distribution list membership cannot be saved. You do not have sufficient permission to perform this operation on this object.
This issue occurs when you try to delete distribution list members who no longer have mailboxes, but are still present in AD DS as disabled accounts. These members cannot be removed from a distribution list by using the Distribution List Membership tool in Outlook. These members are only visible to the owner of a distribution list when the membership list is viewed.
To resolve this issue, follow these steps:
Click Start , point to All Programs , point to Exchange Server 2010 , and then click Exchange Management Shell .
