Can you get Exchange With a technet subscription? I was hoping to find the 32 bit but yet to have, I dont have 64 Bit capable server hardware
Exchange is available through technet as far as I know, however the 32 bit may only be available through MSDN (not 100% sure about that as I don't hold my company's Technet/MSDN accounts at the moment). I know through my VLSC I can get the 32bit exchange because we purchased exchange 2010, but again that isn't a public resource.
As far as your google apps question goes, yes this would work, just know that you are limited by not getting the outlook connector, and can have a max of 50 SMTP addresses.
