Symptoms
Consider the following scenario:
-
You create a distribution group in a Microsoft Exchange Server 2010 environment.
-
You add a user whose mailbox is disabled into the distribution group.
-
You make another user the manager of the distribution group.
-
You assign the MyDistributionGroups role to the manager user account.
-
You log on to Office Outlook 2007 or Outlook 2010 by using the manager user account.
-
You try to remove the user account that has the mailbox disabled from the distribution group.
In this scenario, you cannot remove the user account. Additionally, 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.
Note You can run the New-ManagementRoleAssignment cmdlet to assign a management role to a user account.
Cause
This issue occurs because the MyDistributionGroups role configures the read scope to MyGAL. If the mailbox of a user account is disabled, the user account does not belong to the list. The Address Book Service cannot find the user account when it tries to delete the user account that belongs to MyGAL. Therefore, the user account cannot be removed.
Resolution
To resolve this issue, install the following update rollup:
2579150 Description of Update Rollup 4 for Exchange Server 2010 Service Pack 1
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
Workaround
To work around the issue, perform one of the following steps:
-
Remove the user account that has the mailbox disabled by using theExchange Control Panel (ECP).
-
Follow the Resolution section that is mentioned in KB article 982349. However, the solution grants the user account permission to manage all distribution groups instead of the groups that are owned by the user account.
