So what are the excluded departments using? Hosted Exchange? I'm going to go out on a limb and assume that whatever solution they're using isn't any more secure. Even if you host your own mail servers inside Fort Knox, and hire and vet everyone who goes near those servers, you still have all the same trustworthiness problems. On the other hand, I'm probably missing something there, since Google somehow failed to convince them to stay on board.
