| Microsoft Exchange ActiveSync

The Exchange ActiveSync for Business Mail module provides a premium solution for accessing mail, contacts, folders, tasks, and calendars on mobile devices. Having licensed the ActiveSync protocol from Microsoft, Business Mail is able to provide the same connectivity that is available through Microsoft Exchange.


ActiveSync provides the highest level of integration for the latest mobile devices including iPhone/iPad, Android and Windows Phone 7. It is also available on most other mobile platforms.

ActiveSync is able to negotiate changes and updates protocol uses a technology that is often referred to as “Push”.

The “push” technology means that changes that are made on the mobile device are synchronized with the Business Mail server (and vice-versa) without requiring polling.

ActiveSync is also a very efficient protocol and minimizes the amount of data that is sent over the mobile network.


Business Mail provides other protocols like CalDAV, CardDAV, SyncML and IMAP and these protocols can be configured to provide a similar experience to ActiveSync.

Unfortunately, these protocols do not integrate together to provide the same experience as ActiveSync, and require the configuration of multiple accounts on the mobile device.

In most configurations, the protocols are not able to provide the same end user experience on the device.

ActiveSync, on the other hand, uses a single account to provide access to rich messaging (Messages, Contacts, Calendar, Tasks, Folders, etc) without needing to configure different services.
