Virtual Exchange & NAT'ing

A virtual server currently has Exchange installed on it with load balancing on our network. Each NIC has its own IP address and they want one external address for it to NAT to.  Looking at our ASA, we can't overlap addresses...meaning I get an error when I try to NAT 2 internal addresses to 1 external.  How can this be accomplished?

What version do you have? It can be done with an special configuration on 8.2. If you are in version 8.3 or higher you may want to look at Many to Few NAT configuration.

PAT fixes 99% - post your config for review.
