I've got some code to BCC a recipient based on the who the message is
being sent to. It works great on about half of the computers I try it
on, and about half doesn't run through the code at all.
The clients are all Outlook2003, on WindowsXP.

The code is in ThisOutlookSession, but it simply ignores the code on
several computers. Does someone know of a setting or registry setting
that is causing the code to be ignored?

Thanks
