How NXPowerLite for Microsoft Exchange works

Summary

Email attachments are often much larger than they need to be. NXPowerLite makes them smaller by removing any excess baggage and converting graphics to the most appropriate file format and resolution. Optimized attachments remain in their original format, and will be visually and functionally the same as the original. They don't need to be decompressed or re-hydrated, and there's no need for special viewing software - so they can be opened and edited by anybody.

Note: NXPowerLite for Microsoft Exchange uses the same underlying optimization technology as our successful File Server and Desktop products, which have been used by millions of customers around the world.

Components of NXPowerLite for Microsoft Exchange

NXPowerLite for Microsoft Exchange consists of two main components:

  • NXPowerLite Exchange Dashboard: This is used to connect to the Exchange Server, configure your optimization run and view reports.
  • The NXPowerLite Exchange Optimizer Windows service: This maintains the connection with the Exchange server and manages all aspects of attachment processing.

Both of these can be installed and run on any machine satisfying the system requirements; they do not need to be located on the Microsoft Exchange server.

How the NXPowerLite Exchange Optimizer Windows service works

NXPowerLite for Microsoft Exchange works by replacing supported files attached to emails with smaller versions. Once started, the service will run in the background until it has completed optimization of all the configured mailboxes. To run it again, it will be necessary to open the Dashboard again and restart it manually - it will not automatically restart.

Once configured using the Dashboard, the service iterates through each mailbox in turn. Inside each mailbox, it scans each folder looking for mail items. For each mail item, it determines whether there are any supported and configured attachments and replaces them with optimized versions. Please see the diagram below for a detailed overview of the optimization process.

 

Items not optimized

By design, NXPowerLite for Microsoft Exchange will not currently process the following:

  • Emails that are less than 7 days old.
  • Unread and draft emails.
  • Non-email items - for example, calendar, contact, appointment and task items.
  • Inline attachments.
  • Items in system mailboxes.

 

Note: NXPowerLite for Microsoft Exchange will not compact the underlying database. In order to reclaim actual disk space, a separate process is required. Further information on this can be found by searching Microsoft's support pages.
