Thanks! I am just automating an Excel ss so that when something is
received or ready to ship, it sends out a quick message alerting the
appropriate people. Seems to be working so far, but our IT guy
(anti-Windows everything) is leery about security.

Seems that I didn't understand your question the first time. If you're
talking about CDO 1.21 then it doesn't matter whether you're automating
Outlook directly or via CDO. And if Outlook is installed and configured then
I can't imagine that it should be more unsecure to use it.

What I was talking about is the security feature that applies to both: When
you try to send an e-mail or access one of the blocked properties (like
e-mail addresses) from a outside of Outlook then a message box pops up. To
avoid that I recommended the Redemption.
