You cannot change the ownership of a distribution group in Exchange Server 2010 SP1


Consider the following scenario:
  • You install Microsoft Exchange Server 2010 Service Pack 1 (SP1).
  • You start the Exchange Management Console (EMC).
  • You create a distribution group.
  • You view the properties of the distribution group.
  • On the Group Information tab, you try to add a user to the Managed by group.
In this scenario, you may receive an error message that resembles the following:
You don't have sufficient permissions. This operation can only be performed by a Manager of the group

Note This issue does not occur in Microsoft Exchange Server 2010.


This issue occurs because the EMC cmdlet does not include the -BypassSecurityGroupManagerCheck parameter.


To work around this issue, follow these steps:
  1. Run the following Exchange Management Shell (EMS) command in which dl_name is the name of the distribution group, and user_name is the name of the user whom you want to add:
    Set-DistributionGroup -Identity dl_name -ManagedBy user_name -BypassSecurityGroupManagerCheck
  2. Force Active Directory Domain Services replication.
  3. Open the EMC, and verify that the user was granted ownership of the distribution list.
