This is an Outlook client issue. Mary, who wants to share her calendar with Joe, would open Outlook on her workstation, right click on the Calendar shortcut in the Outlook bar and select properties. Then she would select the permissions tab, select "add" and select Joe.<br>Then Joe would open the control panel on his workstation, double click "mail and fax", select the properties of the Exchange server and on the Advanced tab, select Add to open Mary's mailbox. Because permission is only given on the Mary's calendar, that is all that Joe will see.
