I'm developing an Outlook add-in in VB using VS 2005 and VSTO 2005 SE. For
some reason, I have formating information with the message, and I understand
that Outlook will attach a Winmail.dat file. I also understand, that the
Winmail.dat file will show up as an attachment for the recipient, if he/she
doesn't use Outlook as an e-mail client.

My problem is if the sender attaches a file to the message, Outlook will
embed it in the Winmail.dat file.

My question is, whether it is possible and how to force Outlook from my
add-in not to embed the original attachment in Winmail.dat, but keep it as a
separate attachment besides Winmail.dat. (Other words, I want the recipient
to receive two attachments, the first is the original file that the sender
attached and the second is Winmail.dat with the formating information, but
not the embedded original attachment.)

Thank you.
