Uhm, no one ever said anything about a production environment, as he was just inquiring about the configuration and setup. Considering Exchange 2006 is just two weeks from RTM, it's a fairly legit question. Volume release may be pushed back to late December or first of the year, but it's just around the corner.

...RIM has had plenty of time with the beta to make it compatible. It was feature complete a while back, if I'm not mistaken. They did a good job with Desktop Manager and Office 2007 (for the first time, RIM met a launch date with support), so it's somewhat disappointing they would miss the launch of an enterprise product by 2-3 months.
