I would recommend Server 2008.MVP Exchange Server

Hi John, First of all, thank you for your quick response. But I need some "official" information/documentation for argumenting this decision. Could you tell me some links, explaining the benefits of installing 2008 instead of 2003 ? Thanks again. edgee

This article has explained some good reasons why we should use windows 2008, and also provide some valuable official links for you
