Beat me too it, I was actually starting to setup RM two nights ago but go side track, had planned to blog about it, but this was still helpful since I haven't started setting up the exchange portion.

Very cool to see you got this working!  We've added some other fun supportability features in SP1 which will make it easier to diagnose issues.  Stay tuned for a blog post on it.
