One of these days I'll be forced to do the same setup you described.
Right now the only solution I've come up with is this:
The exchange users should be declared as aliases for addresses in a
subdomain, like mary@???
then you have two possibilities:
Either declare a new MX for the domain exchange.example.com and exim
will route mails to it as long as it's declared in relay_to_domains
Or, if you don't want your Exchange IP address publicly available then
you can setup an ordinary smart_host router for the above subdomain.

Anyone, feel free to jump in the wagon, as I'm sure there must be
another solutions for this issue.
