I'm sure glad you guys posted here recently
otherwise, I wouldn't have found this blog'n'thread.
Extraneous comment for Outlook buffs: Check TR and the 'net for folks having problems with Outlook in an Exchange environment. Tons of weird problems that very good admins have trouble resovling. MS has it's own bugginess, so I find that any problems with Evolution are at least equaled by those with Outlook.
Of course, if your business is using MS wares, you'd probably want Outlook. If you are in a *nix shop, Evolution might be a good option. I don't understand the bashing and defensiveness, at least in this particular thread. Cheers for all of the other discussion (oh, and the article too).
