SITUATION: I am attempting to enable the ability for specified users to edit the membership of Exchange 2010 distribution groups via Outlook 2010. I have configured permissions via RBAC for them to be able to do this by following the instructions and running the script found here:
http://msexchangeteam.com/archive/2009/11/18/453251.aspx
After running the script, users specified as group managers are able to edit group membership through the ECP. But when they attempt to do so via Outlook, they receive the same message that they would see if the permission to edit group membership was not enabled:
"Changes to the public group membership cannot be saved. You do not have sufficient permission to perform this operation on this object."
QUESTION: Does anyone have any idea as to why we are still unable to edit group membership via Outlook, when all the permissions appear to be enabled doing so?
