I was able to get this to work. It required creating a mail profile in
Control Panel for my GM, and setting it to allow me to choose which
profile to use when I start Outlook. I then start Outlook and choose
the GM profile. In there, I create a simple rule for notes sent to the
GM to forward (or form a simple message) to me. I can then exit
Outlook, set Mail profiles back to "always use this profile" to the
default profile, and now messages sent to the GM will be forwarded to
me.
