I need to find out when a user added an entry to a calendar? Is there a log file on the Exchange or Active Directory server that I can look at? I don't see anything on the calendar entry itself.

Hi Lee, You can select Calendar in Outlook -> View menu -> Current view -> Outlook Data file and you will be able to see all appointment in list format. Now select the Created field in Field Chooser to get create time of appointment. http://blogs.msdn.com/outlook/archive/2008/03/28/how-to-sort-by-anything.aspx
