source replacement for Microsoft Exchange? It can be Linux of MS Based. I'm looking for a system that offers group calendars that are flexible and can be shared for scheduling meetings, etc. It is for a new, extremely poor, nonprofit organization. They simply cannot afford M$ and Exchange. I've heard there are solutions in Linux, but the ones I've found are barely cheaper than Exchange. So I'm looking for something that is freeware or open source to use instead. Any help would be greatly appreciated.
