[ActiveDir] Problem with DL owners not able to modify lists

[Cariglia, Daniel]

Hello,               Having a rather odd problem with distribution lists, some owners can modify the lists while others cannot.  It does not seem dependent upon which GC their Outlook client uses.  Nothing has changed in the domain or forest recently and everything was working fine until about a week ago when some owners started reporting the problem.  They are shown as the owner in the Global Address List as well as in ADUC with the “manager can update membership” box checked.  They get an error that states “changes could not be saved, you do not have sufficient permissions to perform an operation on this object”.  I have compared permissions of managers of lists who are experiencing the problem and those who are not having issues and they are identical.  Any ideas would be appreciated.   Dan
