OK, only people in IT departments want integrated solutions. Except they're the ones buying the software. So what's the problem? Integration is not a bad thing

OK, only people in IT departments want integrated solutions. Except they're the ones buying the software. So what's the problem? Integration is not a bad thing. If you don't like the way Microsoft does it -- whether it be the quality of their implementation, or their disregard for standards compliance, or whatever -- that's cool, and I don't even disagree. But business decisions are made based on the bottom line, not on ideology. If Exchange meets the business requirements, and is cheaper to administer than a hodgepodge of other technologies, pragmatically it just doesn't matter if it doesn't implement IMAP exactly to spec. I'm not a big fan of MS, but they're just giving the market what it wants here. If you can do better, please do.
