Microsoft ActiveSync 4.5
ActiveSync is the latest software release for synchronizing Windows Mobile-based devices with Windows XP.
Microsoft ActiveSync provides a great synchronization experience with XP-based PCs and Microsoft Outlook right out of the box. ActiveSync acts as the gateway between your 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 so that you can keep your e-mail, calendar data, notes and contact information updated wirelessly when you’re away from your PC.
