Direct Push keeps a mobile device current over a cellular or wireless network connection. It notifies the mobile device when new content is ready to be synchronized.

For Direct Push to work, the mobile device must be Direct Push capable. These devices include mobile phones that are produced by Microsoft Exchange ActiveSync licensees and that are designed specifically to be Direct Push compatible.

By default, Direct Push is enabled in Exchange The Exchange server monitors activity on the user's mailbox and sends a response to the mobile device if there are any changes, such as new or changed email, calendar, contact, or task items. If changes occur within the lifespan of the HTTPS request, the Exchange server issues a response to the device that states that changes have occurred and the device should initiate synchronization with the Exchange server.

The device then issues this request to the server. When synchronization is complete, a new long-lived HTTPS request is generated to start the process again. This guarantees that email, calendar, contact, and task items are delivered quickly to the mobile device, and that it is always synchronized with the Exchange server.

This request is known as a PING. The request tells the server to notify the device if any items change in the next 15 minutes in any folder that's configured to synchronize.

The mobile device then stands by. The minute time span is known as a heartbeat interval. The mobile device receives this response, resumes activity known as waking up , and issues its request again.
