Safeguard Exchange for Mobile-Device Access

An increasing number of users want to get email while away from their desks. This trend is a far cry from the old days of mainframe-based email, which users retrieved through a terminal. Today's mobile handheld devices, such as Research In Motion's (RIM's) BlackBerry line, Good Technology's Good G100, various Windows Mobile—powered products, and PalmSource's Palm OS—powered Smartphones, are powerful enough to open and edit attachments and handle complex HTML messages. Additionally, a growing number of people carry cell phones that support Wireless Application Protocol (WAP), which lets even these small and relatively dumb devices access sophisticated Web-based applications, albeit at the cost of speed and functionality.

Exchange Server 2003 seeks to meet the growing demand for mobile-device access to Exchange by offering assorted products and services for limited-function devices. The two newest components in this array are Exchange ActiveSync and Outlook Mobile Access (OMA). For information about other mobile-access components in Exchange, see the sidebar "Exchange's Mobile-Computing Support." . . .
