I don't think this is quite the right forum but am unsure about the best
forum for this question so hope someone in here can help me...

My app remotes Word to mail merge letters and then remotes Word to email the
letters via Outlook (using Word's mailmerge-to-email functionality).

Now, if you do a mailmerge-to-email directly in Word then Outlook will not
bother you with security messages as Word is trusted by Outlook. But because
I am remoting Word, the same mailmerge-to-email causes Outlook to prompt the
user to continue for each and every email you send. I understand why that is
required.

However, I would like to write a plug-in for either Word or Outlook that can
be trusted so I can avoid the security messages. Is that even possible? If
so, can someone point me in the right direction?

I have considered doing the mailmerge in my app and directly controlling
Outlook, but that just becomes too much work.

At the moment the calling app is a VB6 app.

Any pointers to reading material gratefully received.

Thanks,
Frans
