ActiveSync is a mobile data synchronization technology and protocol developed by Microsoft, originally released in 1996. There are two implementations of the technology: one which synchronizes data and information with handheld devices with a specific desktop computer (originally known as Handheld PC Explorer), and another technology, commonly known as Exchange ActiveSync (or EAS), which provides push synchronization of contacts, calendars, tasks, and email between ActiveSync-enabled servers and devices.

Exchange ActiveSync is a proprietary protocol and is licensed to a number of mobile device companies, including Apple for the iPhone, Palm for its webOS devices, and Google for certain Android smartphones. Exchange ActiveSync technology is also used by other messaging and collaborative software servers, including Novell GroupWise and Lotus Domino.

ActiveSync was created on 1996-09-10.

ActiveSync was released by Microsoft about 3 years ago, in 2009. ActiveSync allows for the synchronizing of vital computer program information such as email, contacts etc.
