How is it cheaper? I come up with anywhere from $15.00 - $18.00 per user. Albut running on Linux it would be cheaper (no CALs to buy). The other bad thing is the same as Exchange "The Lock In". A plus also to single sign on capabilities. I hear migration from Lotus Domino to Exchange is cheaper. I do not have a validation on that either. Allbut migrating from Exchange 5.5 and 2000 is a pretty large ROI after complete migration. You pretty much don't need the extra support applications that's required for backup and retention.
