I have used Active Directory to set up 5 Global User Groups that I want to be able to assign at the workstation level when dealing with clients personal folders in their mailbox...i.e. I want the Project Managers group to have Publishing Author rights to the Engineers Task folders and Calendars. Problem is, that the Groups do not show up in the list of Users when going to the Permissions tab of the Task and Calendar folder. Did I set up the groups wrong?
