Open Source Exchange

I am looking for an alternative True Source Exchange Mail alternative, that works with Outlook. I have looked at some, but for the Outlook portion to work it requires you to purchase upgrades and that is what we are looking to get away from -= cost. So I am wondering if anyone here knows of a good Open Source software that we could use, Thanks.

Hi sierrawolf,


are all possibilities.   Why must Outlook survive?  Is Evolution not an option?
