Overview

ActiveSync allows a mobile device to be synchronized with either a desktop PC or a server running a compatible software product.

On desktops, ActiveSync synchronizes emails, calendar, contacts and tasks with Microsoft Outlook, along with Internet bookmarks and files. ActiveSync does not support all features of Outlook. For instance, contacts grouped into subfolders are not transferred. Only the contacts which are not in a subfolder are synchronized. In case of Exchange Server, only emails, calendar, contacts and tasks may be synchronized.

ActiveSync also provides for the manual transfer of files to a mobile device, along with limited backup functionality, and the ability to install and uninstall mobile device applications.

Supported mobile devices include PDAs or smartphones running Windows Mobile, Windows CE,[1] BlackBerry 10 or iOS but not the older BlackBerry versions, Palm OS and Symbian platforms. Windows Phone 7 doesn't support desktop ActiveSync synchronization.[2]

Starting with Windows Vista, ActiveSync has been replaced with the Windows Mobile Device Center, which is included as part of the operating system.[3]
