Yes I set up exchange on my own site. Testing server load and email load to see how it performs and if it syncs up with peoples phones ok. Had very limited budget to do this so the server is not very powerful, but for just email it seems to be performing well and I have been using it for a week or so now with zero issues. I am just looking for a few testers to give her a try and see if it performs well for them, the sync, getting and sending emails and such.
