I am writing an Outlook Add-In in C# that will (upon click of a button) take the selected message in the folder and save it to a database. My problem is that I HAVE to have the sender email address. It would be even better if I could get the Reply-To address. Unfortunately the Outlook.MailItem object does not expose those properties and the SenderName property is no help at all. I'm stumped. I have spent hours on this problem and I find it quite ridiculous.
