The information in this article applies to:

Collaboration Data Objects (CDO), versions 1.0a, 1.1, 1.2, 1.21

MORE INFORMATION

Steps to Reproduce Behavior

   'This snippet assumes that you have logged on with a valid profile,
   'and that the Folder it points to will include a number of messages
   'of class IPM.Appointment in order to test the GetFirst(filter).
   '
   objSession.SetOption "CalendarStore", "Outlook"
   Set objCalendarFolder = _
     objsession.GetDefaultFolder (CdoDefaultFolderCalendar)

   Set objMessageColl = objCalendarFolder.Messages
   'Set filter condition of GetFirst to IPM.Note in order to get
   'the first message with a class of IPM.Note.
   Set objApptItem = objMessageColl.GetFirst("IPM.Note")

RESULT:

Examining the returned objects class property reveals that the GetFirst method with a filter set to return only messages of class IPM.Note in fact returns a message of class IPM.Appointment.
