Hi,
First of all, I want to say that all the group are Universal, I have give user ability to manage their group, I even try the -ForceUpgrade switch. I have given user full access on the DL (just in case) and to Exchange Trusted Subsystem too, I have try the cmdlet
Add-ADPermission -Identity <name of distribution group> -User <name of user> -AccessRights WriteProperty -Properties "Member"
The checkbox for "Manager can update membership list" is checked
All my server are on SP2 RU4v2.
I have Try Outlook 2007 and 2010 (online and cached) on the AL, OAB and GAL
The problem is present on all computer from office and home, all connected by Outlook Anywhere, so
Any other idea on what could be my problem for the error : you do not have sufficient permission to perform this operation on this object?
