Key Features

Connect via EWS

NXPowerLite connects to Exchange using the Exchange Web Services (EWS) API and uses our proven compression to ensure email attachments are safely and efficiently reduced.


NXPowerLite is fully compatible with Windows task scheduler meaning you can 'Start' or 'Stop' the service from other events. NXPowerLite will resume smoothly from where it left off.

Monitor Results

NXPowerLite generates comprehensive reports, detailing how storage was being used and the savings achieved by compressing email attachments.

Control growth
Schedule NXPowerLite to periodically scan your Exchange database and it will automatically find and optimize new email attachments added since the last scan, slowing down your storage growth.
Data migration
NXPowerLite makes sure your Exchange storage is as small as possible, so when it comes to migrate it you know you are not moving more data than you need to.
User productivity
Smaller files are easier for users to access, edit and share.
Network traffic
Smaller emails place less burden on the network and transfer more quickly especially over limited connections.
Reduce backup time
Smaller files on front-line storage means you'll have smaller, faster backup and restore windows too.

What size will I need?
Choose based on the volume of storage on your device that is configured for the Exchange database. You will need a licence large enough to accommodate all of the available database storage.
For example: With an 8 TB device that has 4 TB configured for the Exchange database you would need a 5 TB licence. The volume that is currently occupied is not taken into account so in the above example if only 2 TB is occupied you will still need the 5 TB licence.
