           ' Change AppointmentItem to a Meeting. 
           oAppt.MeetingStatus = Outlook.OlMeetingStatus.olMeeting
   
           ' Set some common properties.
           oAppt.Subject = "Created using OOM in VB.NET"
           oAppt.Body = "Hello World"
           oAppt.Location = "Samm E"
   
           oAppt.Start = Convert.ToDateTime("11/30/2001 9:00:00 AM")
           oAppt.End = Convert.ToDateTime("11/30/2001 1:00:00 PM")
   
           oAppt.ReminderSet = True
           oAppt.ReminderMinutesBeforeStart = 5
           oAppt.BusyStatus = Outlook.OlBusyStatus.olBusy  '  olBusy
           oAppt.IsOnlineMeeting = False
           oAppt.AllDayEvent = False
   
           ' Add attendees.
           Dim oRecipts As Outlook.Recipients = oAppt.Recipients
   
           ' Add required attendee.
           Dim oRecipt As Outlook.Recipient
           oRecipt = oRecipts.Add("UserTest1") ' TODO:
           oRecipt.Type = Outlook.OlMeetingRecipientType.olRequired
   
           ' Add optional attendee.
           oRecipt = oRecipts.Add("UserTest2") ' TODO:
           oRecipt.Type = Outlook.OlMeetingRecipientType.olOptional
   
           oRecipts.ResolveAll()
   
           'oAppt.Display(true)
   
           ' Send out request.
           oAppt.Send()
   
           ' Logoff.
