For many, the convenience of accessing e-mail, calendar and contacts on a smartphone is integral to their business' success, and they cann't imagine working without this capability. The protocols that allow this mobile messaging reside in "Exchange ActiveSync," which's an XML-based protocol that communicates over HTTP (or HTTPS) to synchronize e-mail, contacts, calendar, tasks and notes from a messaging server to a mobile device. The protocol also provides mobile device management and policy controls.
A range of devices running Windows Phone 7 and older WinMo releases, but also smartphones such as Apple, HP/Palm, HTC, Nokia, Samsung and Sony Ericsson, and from Google feature EAS.
EAS also allows organizations to protect the data on the devices that connect to their Exchange Server. Data can be protected though policies that enforce data encryption and require PIN passwords on devices, and EAS enables IT professionals to erase all data off a phone that has been lost or stolen.
WinP7 also supports EAS for synchronizing e-mail, calendar events and contacts with Exchange Server -- or any other messaging service or server that supports EAS. "EAS is native to WP7, allowing people to set up and access multiple e-mail accounts and calendars on their phone," says Adam Glick.
