Microsoft ActiveSync 4.2 is the latest synchronization software for Windows Mobile-based devices.
Overview: Microsoft ActiveSync 4.2 is the latest sync software release for Windows Mobile-based devices. 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 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.
