When you run a program that uses the Microsoft Outlook object model to call the Respond method, you receive a warning message. This warning message tells you that a program is trying to send an item on your behalf and asks if you want to allow this.

fNoUI, fAdditionalTextDialog Result
True, True For AppointmentItem and TaskItem:

Response item is returned with no user interface. To send the response, you must call the Send method.

True, False For AppointmentItem and TaskItem:

Same result as with True, True.

False, True For AppointmentItem:

Prompts user to Send or Edit before sending the response.

For TaskItem:

If the Display method has been called, the user prompt appears. Otherwise, the item is sent without prompting and the resulting item is nothing.

False, False For AppointmentItem:

New response item appears in the user interface, but no prompt is displayed.

For TaskItem:

Does nothing.


This Visual Basic for Applications (VBA) example finds a MeetingItem in the default Inbox folder and adds the associated appointment to the Calendar folder. It then responds to the sender by accepting the meeting.

Sub AcceptMeeting()
    Dim myOlApp As New Outlook.Application
    Dim myNameSpace As Outlook.NameSpace
    Dim myFolder As Outlook.MAPIFolder
    Dim myMtgReq As Outlook.MeetingItem
    Dim myAppt As Outlook.AppointmentItem
    Dim myMtg As Outlook.MeetingItem
    Set myNameSpace = myOlApp.GetNamespace("MAPI")
    Set myFolder = myNameSpace.GetDefaultFolder(olFolderInbox)
    Set myMtgReq = myFolder.Items.Find("[MessageClass] = 'IPM.Schedule.Meeting.Request'")
    If TypeName(myMtgReq) <> "Nothing" Then
        Set myAppt = myMtgReq.GetAssociatedAppointment(True)
        Set myMtg = myAppt.Respond(olResponseAccepted, True)
    End If
End Sub

If you use Microsoft Visual Basic Scripting Edition (VBScript) in an Outlook form, you do not create the Application object, and you cannot use named constants. This example shows how to perform the same task using VBScript in a CommandButton Click event.

Sub CommandButton1_Click()
 Set myNamespace = Application.GetNamespace("MAPI")
 Set myFolder = myNamespace.GetDefaultFolder(6)
 Set myMtgReq = myFolder.Items.Find("[MessageClass] = 'IPM.Schedule.Meeting.Request'")
 If TypeName(myMtgReq) <> "Nothing" Then
     Set myAppt = myMtgReq.GetAssociatedAppointment(True)
     myAppt.Respond 3, False, True
     MsgBox "You have no meeting requests."
 End If
End Sub
