Well there isn't an exchange 2006, first of all.
Lets see what I can come up with....
- Never had a virus take down a groupwise server
- Never had a virus propogate through my groupwise client that infected 60,000 users and 1000 Windows servers like I have seen Exchange do, shutting down worldwide datacenters for 3 days while cleanup takes place.
- GroupWise is solid. Get GroupWise up and running and you don't have to think much more about it. I Can't say that for exchange, it requires constant babysitting.
- Why would you want to run a Legacy product like Exchange? It's been out since 2003. GroupWise 7 was released just last year with a MAJOR service pack released just a couple months ago (yes in 2006) that added some huge features.
- Exchange 2007 is in the 'major media hype' phase right now. I wonder if you install Exchange 2003 now, what will the pain be to upgrade it? If history repeats itself, every new version is a complete revamp of your network.
- On the contrary, GroupWise can be upgraded in place in about 1 day (being very conservative). No network overhauls and usually doesn't require new hardware.
- GroupWise can run on Linux, Windows, or NetWare.. What's your favorite platform? Can you get Exchange to run on Linux? I don't think so.
I'm sure if you ask in the Exchange forum (Which you've probably already done), you'll probably hear a lot about "well Exchange is the market leader" and "Exchange 2007 is almost out" and "Can't wait for Exchange 2007" blah blah blah".
Thats all I have right now.
