Still anxious and fidgety about moving towards the first ever 64-Bit version of Exchange? Get the lowdown with a detailed explanation, downloadable on Microsoft’s web site here:
For now, it seems as if 64-bit will become the standard operating system for servers while 32-bit Windows XP/Vista will remain the majoer operating system at least until 2010 when all software and hardware vendors catch up. Personally I would love to run my memory and I/O hungry graphics applications on 64-bit but this might take a while. My Exchange server will run faster but I am not sure how much this will really benefit clients who get good enough service these days. For larger Exchange shops, however, migration will be a very smart move worth the money.
