The server software is used to transfer e-mail and older corporate data to and from the Blackberry handheld device.
RIM said Enterprise Server 4.0 would provide users with better handheld asset control, easier deployment, additional wireless security and simplified application development.
In terms of changes to deployment, RIM said the new server would have full support for cradle-free wireless working. According to the supplier, this will allow IT departments to maintain full control over Blackberry devices without the need for centralised IT deployment.
Other changes to the administration aspect of the device are designed to help IT departments manage which applications can be installed on handhelds remotely.
RIM said it was also planning to simplify software development for the Blackberry.
Enterprise Server 4.0 is likely to be released later this year.
