We have been trying (thru code\no client) to create an email on an Exchange 2003 server that is located in my network, from a webpage in the cloud. We currently do this in-house successfully. Obvious differences doing this on opposite sides of the corporate firewall, but authentication to the server seems to be okay, but the SMTP email generation fails. I'd appreciate any nuggets of wisdom! Thanks.

I recommend that you post your question to the Development forum. http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/threads And when you do so, include a lot more detail on what you're trying to do and how you're doing it because I really can't figure that out from your post.
