(Exchange) ActiveSync is a client protocol developed by Microsoft that lets you synchronize a mobile device with a Microsoft Exchange mailbox.

The Exchange ActiveSync protocol is based on HTTP and XML and lets mobile phones access an organization's information on a server that's running Microsoft Exchange. Exchange ActiveSync enables mobile phone users to access their email, calendar, contacts, and tasks, and to continue to access this information while they're working offline.

Exchange ActiveSync provides the following:

  • Support for HTML messages
  • Support for follow-up flags
  • Conversation grouping of email messages
  • Ability to synchronize or not synchronize an entire conversation
  • Synchronization of Short Message Service (SMS) messages with a user's Exchange mailbox
  • Support for viewing message reply status
  • Support for fast message retrieval
  • Meeting attendee information
  • Enhanced Exchange Search
  • PIN reset
  • Enhanced device security through password policies
  • Autodiscover for over-the-air provisioning
  • Support for setting automatic replies when users are away, on vacation, or out of the office
  • Support for task synchronization
  • Direct Push
  • Support for availability information for contacts
  • remote wipe to clear all data from a lost or stolen mobile phone
