Have you tried setting up message synchronization under Synchronization and Storage? That will copy down the files from the server to the local machine as well as leave them available on the server. While it does duplicate messages and increase storage requirements, it does provide a local copy for offline use and it makes it a lot easier to archive the messages if they are already locally available.
