Comment talk to an M$ sales agent (Score 1) 293
Get permission from your company if you want, but call M$ and say you are thinking about switching to exchange and want to know if they can help with a trail run. MSDN is great, but not free, and this way you have access to M$ support during your inital setup. Run it a few months, play with it, break it (on purpose if you have to), have M$ help you fix it again, then make sure you thank the sales agent profusely as you uninstall and decide not to buy...
