Found the solution. It required a packet sniffer and several settings changes to the RT to resolve. Not an access point issue. Not an Exchange policy issue. First, I disagree with the assertion that the RT is unsuitable as a companion device in the Enterprise, when a full PC is also available. I'll continue to evaluate it as such. Pro isn't required as a second device. Second, Office licensing is a non-issue as a companion device in our environment. The users already have a full license under our Select agreement that allows for a second device. Third, part of the evaluation process is to perform unbiased testing. Not unlike movie reviews, where bias comes into play. It's unfortunate that some of you fall back on "Microsoft never intended for the RT to do X....". Pure, uneducated speculation. I read, researched, and then purchased one to form my own impressions. You don't need to defend MS...hold them accountable for support, advertising, and keep tension on them to perform. Attitude goes both ways.
