Well, I've seen enough things different/modified/broken in Office 2007 so I
can see that it might be something new there, but without knowing more about
what's happening and how they're trying to do things I can't express any
sort of opinion. I do know that some things that weren't supported but
worked in the past may not work now, but that's what happens when you use
unsupported methods.

About the only thing I can think of that might be helpful is for either the
vendor of the ActiveX control or your company to file a support incident
with MS and let them run with that ball and see what they come up with.

Hi Ken,

It is definitely something to do with Outlook 2007. I uninstalled the
antivirus software and created a standalone test application that
exercises
the third party ActiveX Control and I can definitely send messages while
Outlook 2007 is running from the test application (different process).
Which
leads me to believe that Outlook 2007 is doing something to prevent a
message
from being sent from the same process? I have some further testing to do -
but at this time I think it is something to do with Outlook 2007. Again
there
are not any problems with Outlook 2003 and below.
