Hmmm, interesting perspective. The "problem" that you guys ran into was something that I actually needed. Because allowing a user to check their private email bypasses the virus protection on your Exchange server, my organization chose to implement a policy prohibiting this. We enforced this in two ways, blocking the port on the firewall that allows this, and using ProfGen to overwite all existing profiles with one that only includes the Exchange server.
Your fire chief may pissed at losing his profile, but just imagine what he, and others , will think if he introduces a virus that bring your server to it's knees. We suggested to our management that they forward their personal accounts to their work account, thus making everything come through the Exchange server virus checker.
