I purchased MAPS and have a test network at home. I wanted to build an Exchange server, but the only version included in my Action Pack is 64 bit and the hardware I am using will only support 32 bit. I downloaded the 32 bit version from Microsoft, which I read is not for production and not for sale, but I constantly get an annoying message about loading a product key and I only have limited days remaining. Is there a product key available for non production Exchange and will I need to rebuild this entire server 120 days after installing? I can learn to deal with the message, but I was hoping to keep my server intact for longer then 4 months. Exchange is installed on Windows 2008 standard.
