Return value

Type: Microsoft.Office.Interop.Outlook.MeetingItem
A MeetingItem object that represents the response to the meeting request.

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.

True, False

Same result as with True, True.

False, True

Prompts user to Send or Edit before sending the response.

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