Not trying to start a flame war, but what would companies use instead?
This is exactly the problem, and I'll underscore it with an inquiry to anyone who echoes the grandparent post...
Amongst the reasons Exchange is as readily used as it is, isn't because Exchange itself is some awesome piece of software. Exchange is part of a bigger ecosystem that incorporates a few major pieces:
--ActiveSync - and more to the point, ActiveSync support from billions of phones and tablets.
--Active Directory - single sign-on through Outlook from a domain user, and the reverse: creating a mailbox also creates a user in AD.
--Outlook - a mail/contact/calendar/task client that has a handful of competitors that excel in one area or another (IMO Zimbra coming pretty close), but still a program whose replacement will require a barricade on the door to keep out the execs who wish to use their torches and pitchforks.
--Self-Hosted - Gmail and company don't count.
I've seen plenty of great answers to one or more of these solutions. I'm a fan of the super-easy-to-use-and-manage IceWarp, but the Icewarp mail client is lacking pretty notably. Google is great if you're okay with them having your mail (many are), but unless there's an on-site version of Gmail, it's not a fair comparison fight. Univention makes a pretty good PDC replacement, but using for its mail server isn't the greatest and mobile device support is lacking. Zentyal and ClearOS are also great for small environments, but scaling becomes a problem.
So, to those who say "Exchange Sucks", I say "fine. Show me a better system that satisfies all of the above criteria, and I will be MORE than happy to take a long, hard look at it." I don't like Exchange, or its CAL structure, either...but "worst except all the rest" seems to apply here.
