There is no mechanism for trusting specific ActiveX controls with regard to the Outlook object model security guard. Perhaps you're thinking of COM add-ins, which doesn't apply here because it's an external program sending the message not an Outlook add-in. See http://www.slipstick.com/outlook/esecup.htm#autosec for more informaton.

Is there any known way around this problem? I've seen nothing in
Technet or the usenet groups in regards to this particular issue.

Did you look at the page I suggested?

I have looked at the page. I am familiar with and already use the
Security described for some custom MAPI apps. The problem is
identifying which control to add to Trusted Code section.

The Trusted Code section applies only to Outlook add-ins, not external applications, which is what you're dealing with.
