It may be that you have a different connection set up for sending and receiving (it may even have the same settings). If you are already connected and you try to send and receive, it drops the current connection to dial your default Email conection.
Try changing the Email connection to the same as the dial up connection you use from your desktop or start menu.
This is a guess, as I don't have OLE set up, so I can't try for you.
Good Luck
