Any user property you create using the Outlook object model will be visible
in one way or another if the user is clever. If you use CDO 1.21 or Extended
MAPI or Redemption (www.dimastr.com/redemption) code to create a user
property (Field) it won't be visible to the user unless they run their own
code to find the Fields or use a tool such as OutlookSpy or MDBView.
