Microsoft ActiveSync 4.5 is the latest sync software release for Windows Mobile-powered devices. ActiveSync provides a great synchronization experience with Windows®-powered PCs and Microsoft Outlook right out of the box. ActiveSync acts as the gateway between your Windows-powered PC and Windows Mobile-powered device, enabling the transfer of Outlook information, 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 PC.*
Changes in ActiveSync 4.5 Beta 2 help resolve 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 PC sync via USB cable, Bluetooth, or infrared connection.
