[SLE] Exchange type server

I know it's a long shot, but we have a customer currently using Microsoft products, and they love the way Exchange works with Outlook. Basically, want I need to know is if their is an Exchange type server for Linux. Something that would do contact lists, etc. for Outlook. I know it's not very likely, but I told them I'd check around. Otherwise, I'll have to try and talk them into going with a web-based alternative. Thanks!
