And yet some more info. I was wrong, OWA is not open to the outside world. Again, no real need here. So, I'm worried this won't work. If not, I had this idea.
1. Create a contact in Exchange for my boss (yahoo, hotmail, etc).
2. Set his mailbox delivery options to "deliver to both forwarding address and recipient" - using this contact.
3. Then set the 'reply to' address for the BB to be his work address.
It'll get forwarded around some but I think it'll accomplish what I'm after.
Any thoughts or comments on this setup?
