> Tell us the cost per user
Cost is hardly just monetary. E.g., if his organisation happens to be a major defence contractor, internal emails will not be going through the internet one way or another so that precludes the use of a third party host, unless they *really* like living dangerously.
And even in monetary terms, I would find it hard to believe that an organisation with a well-manned IT department (i.e., they know what they're doing) would get a cheaper deal than in-premise hosting.
