My workplace is dual-platform, we've got both PC's and Macs galore. My IT guy and I have been pretty excited about Exchange being supported out-of-the-box, but we got pretty bummed when we saw it would only support 2007, not 2004. We've been hoping to deep-six all our Entourage usage, we've had nothing but problems as of late, but we're only running 2004 and probably won't be able to upgrade to 2007 due to a tight budget. What are the possibilities of a third-party software company releasing some kind of compatibility workaround to permit support for Exchange 2004? I'm sure Apple would be less likely to release something like that, otherwise they would have made it compatible with 2004 out of the box.
