AppointmentItem.Respond Method

  • Article
Outlook Developer Reference

Responds to a meeting request.

Syntax

expression.Respond(Response, fNoUI, fAdditionalTextDialog)

expression   A variable that represents an AppointmentItem object.

Parameters

Name Required/Optional Data Type Description
Response Required OlMeetingResponse The response to the request.
fNoUI Optional Variant True to not display a dialog box; the response is sent automatically. False to display the dialog box for responding.
fAdditionalTextDialog Optional Variant False to not prompt the user for input; the response is displayed in the inspector for editing. True to prompt the user to either send or send with comments. This argument is valid only if fNoUI is False.

Return Value
A MeetingItem object that represents the response to the meeting request.

Remarks

When you call the Respond method with the olMeetingAccepted or olMeetingTentative parameter, Outlook will create a new appointment item that duplicates the original appointment item. The new item will have a different Entry ID. Outlook will then remove the original item. You should no longer use the Entry ID of the original item, but instead call the EntryID property to obtain the Entry ID for the new item for any subsequent needs. This is to ensure that this appointment item will be properly synchronized on your calendar if more than one client computer accesses your calendar but may be offline using the cache mode occasionally.

The following table describes the behavior of the Respond method depending on the parent object, and the fNoUI and fAdditionalTextDialog parameters.

fNoUI, fAdditionalTextDialog Result
True, True

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

Same result as with True, True.
False, True

Prompts user to Send or Edit before sending the response.
False, False

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

Example

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.

Visual Basic for Applications 
  Sub AcceptMeeting()
    Dim myNameSpace As Outlook.NameSpace
    Dim myFolder As Outlook.Folder
    Dim myMtgReq As Outlook.MeetingItem
    Dim myAppt As Outlook.AppointmentItem
    Dim myMtg As Outlook.MeetingItem
  
    Set myNameSpace = Application.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)
        myMtg.Send
    End If
End Sub
