Messaging Server supports archiving through the AXS-One archive system. A message archiving system saves all or some specified subset of incoming and outgoing messages on a system separate from Messaging Server. Sent, received, deleted, and moved messages can all be saved and retrieved in an archive system. Archived messages cannot be modified or removed by email users so the integrity of incoming and outgoing is maintained. Message archiving is useful for compliance record keeping, message store management, and message back up. See Message Archiving Using the AXS-One System for more information.
