[Spambayes] Filtered items in Outlook are automatically marked as read

[Powell & Hinkle Engineering]

When I receive any new mail with Microsoft Outlook it puts the mail in my
inbox by defauld, but then automatically forwardes it to a public folder
that can be seen by our entire network. It is necessary for for me to keep
these files marked as unread to keep track of these new messages, which is
how it was set up.  But when the messages are forwarded to this folder the
spam bayes program (binary version .81) filters them, and takes away their
unread status. I've tried to set Spam Bays to scan the new messages when
they are still in my inbox but then they don't get forwarded to my public
folder on the network (which is even more important).  How do I set Spam
Bays, or Microsofs Outlook, to keep these files as unread, in my public
folder, and filtered all at the same time, or is this impossible?

Thanks
