I have a program that uses Outlook for it's emailing, but have run into a slight problem. Most of the emails are generated automatically when certain transactions are made, which means that the user needs to wait until they are sent. Problem is, a couple of them have several large attachments. Thus, serious hang-time while Outlook encodes them. So, I was thinking that I could just pre-encode them and add the encoded text to the email. Anyone know of a way to do this via the Outlook object model? I really don't want to have to switch to generating raw SMTP if at all possible.
