ActiveSync acts as the gateway between your Microsoft Windows-powered PC and Windows Mobile powered device, to transfer Microsoft Outlook information, Microsoft Office documents, pictures, music, videos and applications to and from 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, tasks and contact information updated wirelessly when you’re away from your desktop or tablet PC.

Changes in ActiveSync 4.5 Beta 2 help improve issues related to setup, partnerships, and connectivity with the PC and Microsoft Exchange. In addition, it includes a troubleshooter utility that scans your computer and device to identify problems and offers information and corrective actions to solve them.

ActiveSync 4.5 Beta 2 supports synchronization with a desktop or tablet PC via USB cable, Bluetooth, or infrared connection.
