What is Exchange ActiveSync?

Exchange ActiveSync is a protocol which allows mobile devices to synchronize data with Exchange mailboxes. Synchronizing is a process of reconciling data between a device and the appropriate Exchange mailbox. The protocol synchronizes your mail, calendar, contacts, and tasks over the air with Microsoft Exchange Server. This connection can be done directly from the device using Wi-Fi or a cellular network.

Traditional connections to a network-connected computer synchronize via the desktop ActiveSync client using the cradle, USB, infrared, or Bluetooth. Exchange ActiveSync is an additional server-based synchronization agent that removes the dependency on a desktop computer, using the wireless capability of the device. The two methods of ActiveSync can be used in combination or independently.

Your device must be properly configured to connect to the Internet before using Exchange ActiveSync (VPN is not required).

Exchange ActiveSync is supported on many mobile devices. Check your device's documentation for verification of Microsoft's Direct Push technology.

For more about ActiveSync, see the Microsoft TechNet Exchange ActiveSync FAQ.
