As of this weekend the beta version of ActiveSync 4.2 is available for download.
“Microsoft 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 from your desktop to 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, Notes, and Contacts updated wirelessly when you’re away from your PC.”
No change-log so far. So please try for yourself on a non-production machine with a non-production Windows Mobile device. Thank you.
