Problem setting delegates
 

Hi, Our organization has Exchange2k3 and Outlook 2k3. Users are recieving an
error message while trying to set delegates

"Delegates settings were not saved correctly. Unable to activate
send-on-behalf-of list. You do not have sufficient permission to perform
this operation on this object."

This is a problem on some computers and not others. Their Outlook clients
have service pack 3.

Any help would be appreciated.
