DLL Implemented In

Syntax

        [Visual Basic]Property MDNRequested As Boolean
        [C++]HRESULT get_MDNRequested(VARIANT_BOOLpVal);
HRESULT put_MDNRequested(VARIANT_BOOL Val);

Parameters

pVal
Returns the value of the MDNRequested property as a reference to a VARIANT_BOOL.
Val
Sets the value of the MDNRequested property to the value of the VARIANT_BOOL.

Remarks

An MDN is a request for disposition information from a recipient after the message has been successfully delivered. This disposition might include whether the message was displayed, printed, or deleted without display, or if a recipient refused to send MDNs. The message sender or an intermediary Message Transfer Agent can request MDNs. The returned MDN report message is nested in a message with Content-Type of multipart/report. RFC 2298 describes MDNs, their function and format.

To request an MDN for a message, set the urn:schemas:mailheader:disposition-notification-to header field to the sender's e-mail address. Optionally, set the urn:schemas:mailheader:disposition-notification-options header field to the appropriate value. Then send the message. To remove a previously added MDN header field, delete it using the IMessage.Fields.Delete method.
