I've been on a committee to determine which product is the best for email. Currently where I work, we use Exchange 2003. Never had a problem with it. Other places use Lotus Notes. From our testing, Exchange 2003 is way better. Then the group that claims Lotus is better is saying how Lotus has all these ubercool add-ons, but that is beside the point because the focus is to determine which is the best overall EMAIL system. That said, getting back to the add-ons, Lotus has some bulletin board add-on where people can sell all sorts of things on there. I realize its just a database, but it hooks right into Lotus and is clean from what I've seen. Does anyone know if Exchange has any cool add-ons like this I have missed?
