MORE INFORMATION

Steps to Reproduce Behavior

   'Following is the VBScript code to reproduce the behavior:
   'This sample assumes that the CDO (1.1, 1.2, 1.21) library is installed
   'on the test system and that a profile named "Microsoft Outlook"
   'exists.

   Sub but_OnClick
     Dim objSession
     Set objSession = CreateObject("mapi.session")
     objSession.Logon "Microsoft Outlook"
     MsgBox objSession.Inbox.Messages.Count 'This fails w/Access Denied
     objSession.Logoff
   End Sub

NOTE: This issue does not occur with all properties and methods; some operations (like sending messages) and some properties operate as expected.
