I have a shared mailbox and would like to retrieve the appointments from the Shared Calendar. How can I acheive this?
You should be able to get connect to a shared calendar like this.
// load the default calendar
CalendarFolder calendar = CalendarFolder.Bind(Service, WellKnownFolderName.Calendar, new PropertySet());
FolderId folder= new FolderId(WellKnownFolderName.Calendar, "firstname.lastname@example.org");
CalendarFolder calendar = CalendarFolder.Bind(Service, folder);
