OWA Public Control
The OWA Public Control allows you to delegate permissions on Outlook Public Folders via Outlook Web Access. The Public Folder directory is displayed in a tree view format in which folders can be expanded or minimised to show subfolders. Provided that you have sufficient permissions to a folder, you are then able to add users as delegates and grant them roles that give them specific access permissions to the folder. Other functionality include being able to remove delegates from a folder as well as adding and removing multiple delegates to and from subfolders.
