ActiveSync is the latest sync software release for Windows Mobile 5.0-based devices.

Microsoft ActiveSync provides a great synchronization experience with Windows-based PCs and Microsoft Outlook right out of the box.

ActiveSync acts as the gateway between your Windows-based PC and Windows Mobile-based device, enabling the transfer of Outlook information, Office documents, pictures, music, videos and applications from your desktop to your device.

In addition to synchronizing with a desktop PC, ActiveSync can synchronize directly with Microsoft Exchange Server 2003 so that you can keep your e-mail, calendar data, notes and contact information updated wirelessly when youre away from your PC.
