Since upgrading our Exchange 2010 servers to SP3 Update RU4, a user has complained that they can no longer modify members of a distribution group.
As an administrator, I cant modify it either, but if I add myself as an owner to this group, which is a requirement for any group you modify\create now, I can modify it. If I make the user an owner, they still cannot modify membership. This is the case for new of existing groups whether the user is a member or not.
The error the users gets is as follows:
Pre SP3, I'd run the following PS script:
Add-ADPermission -Identity "<Group name>" -User <User name> -AccessRights WriteProperty -Properties "Member"
But this doesn't work now.
