Exchange ActiveSync, the built-in, highly scalable mobile solution in Exchange Server 2003, has helped make mobile messaging available to an ever-growing portion of the workforce. This in turn has changed increasing amounts of lost time into productive time. Exchange ActiveSync pushes email, voice mail, fax, calendar, contacts, and tasks to a mobile device as soon as they arrive at the server. This means that, even while traveling, employees are never out of touch.
Exchange ActiveSync is supported on a wide variety of mobile devices. This includes devices that run the Microsoft Windows Mobile operating system, as well as devices and software from DataViz, Nokia, Sony Ericsson, Palm, Motorola, and Symbian.
