Saving an email as an MSG after a send

[Mystery Man]

What I want to do is send an email and then save the mailItem.

ie

mailItem.Send();
mailItem.SaveAs(fileName, Outlook.OlSaveAsType.olMSG);

However, this does not work because the item has been deleted

If I save then send, all works fine except the message is shown as not being sent.

mailItem.SaveAs(fileName, Outlook.OlSaveAsType.olMSG);
mailItem.Send();

What is the simplest way of getting the sent message as an MSG?
