Microsoft ActiveSync 4.5 is a new software update release for Windows Mobile powered devices that provides a great synchronization experience with Windows-powered PCs and Microsoft Outlook.

In addition to synchronizing with a desktop PC, ActiveSync allows you to synchronize Microsoft Outlook information directly with Microsoft Exchange Server 2003 and Microsoft Exchange Server 2007, 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.*
