I'm not sure my suggestions will be gratefully received. :)
Don't do that. CDO ("Collaborative Data Objects" are a COM/ActiveX wrapper
around MAPI, which in turn is a Microsoft-proprietary wrapper around SMTP,
a well-established, well-tested standard for email sending, a Simple Mail
Transfer Protocol. Every time MS decides they don't like the way something
works, they change their interfaces, breaking your software. SMTP, on the
other hand, Just Works (tm). There are a few gotchas with sending mail,
depending on whether the receiving email server requires SSL,
AUTHentication or other handshake protocol, but they can all be tested and
debugged. MAPI, not so much.
This isn't just theoretical, or an "I Hate Microsoft" screed. Several
times, I've had MS ship "updates" to their software that broke their MAPI
implementation, requiring workarounds or rewrites. To the great unhappiness
of my clients. Since then, I've used SMTP, with Blat or West-Wind's Client
Tools, with dozens of customers across the country, for well over a decade
and a half.
So, when you say, "It breaks when I do that," I'm forced to reply, "Don't
do that."
MAPI Bad, SMTP good.
Take a look at http://fox.wikis.com/wc.dll?Wiki~AutomatedEmail~Wiki as a
good starting point.
