Envoyer un e-mail avec des pièces jointes avec Exchange 2003 et WebDav

Question

J'essaie d'envoyer des e-mails via Exchange Server 2003 avec WebDav. Envoyer un e-mail simple n'est pas un problème, mais je n'arrive pas à envoyer un e-mail avec des pièces jointes. Je reçois la pièce jointe au serveur mais je ne sais pas si je la mets au bon endroit. Donc mes questions sont: 1. Où sur le serveur la pièce jointe doit-elle être téléchargée? 2. Comment associer la pièce jointe à l'e-mail?

Un exemple de code serait très apprécié.
