Using Outlook 2003 from Space
 

On the Space Shuttle and the International Space Station they use Microsoft Outlook 2003, but not quite in the same way that us earthbound Earthlings do. The space shuttle Atlantis is orbiting the earth right now and the crew exchange emails with the ground a few times each day. Bandwidth is a constraint and you don't want the busy crewmembers bothered with spam or unnecessary messages so NASA has a special system in place. The crew use fairly standard laptops running Microsoft Outlook (currently Outlook 2003) with Exchange Server as the email host, but they don't link to the server using any of the standard methods.
