There are 2 main type of push e-mail, Microsoft Active-Sync and Openhand.

Miscrosoft Active-Sync
You can use Miscrosoft Active-Syns to synchronise the data between you handset and your Exchange server.

This allows a copy of the data stored in your calendar, contacts and e-mail to be stored on your portable handset. After one syncrhonisation the handset then simply updates what information has changed since the previous synchronisation.

To set this up can be rather complex to the average user and so LakesideIT can always come and configure your phones to synchronise to your server and advise accordingly.

OpenHand
The main advantaes to Openhand is thet they offer two solutions depending upon whether you have your own Exchange server or not.

Their software works by accessing the data stored live, rather than having copies of the data stored on your handset. This offers greater security should you lose your phone but it also allows you to reduce your data useage to approx 3Mb per month depending upon personal useage. As most data tariffs charge you for your useage this could be a great cost saving benefit to yoru organisation.
