MailItem.OriginatorDeliveryReportRequested Property (Outlook)
Published: July 16, 2012
Returns or sets a Boolean value that determines whether the originator of the meeting item or mail message will receive a delivery report. Read/write.
Each transport provider that handles your message sends you a single delivery notification containing the names and addresses of each recipient to whom it was delivered. Delivery does not imply that the message has been read. True if the originator requested a delivery receipt on the message.
The OriginatorDeliveryReportRequested property corresponds to the MAPI property PidTagOriginatorDeliveryReportRequested.
