Exchange Mailbox Level Features

With Exchange Mailbox Level backups, you can:

  • Use Exchange Web Services (EWS) that allows multi-threading.
  • Restore directly to a mail message (.msg) file or to an Outlook Personal Storage Table (.pst) file.
  • Run the software from any computer with web access so the agent does not need to be installed on the Exchange server.

Exchange Mailbox Level backups allow you to back up users' mailbox data for granular restores. Mailboxes, contacts, and even individual mail messages for a user can be restored on an individual basis, or in bulk, to provide flexibility in the choices you have when reinstating a user's email.

Mailbox level backup sets are best used as a data-archiving utility, to keep a record of the emails sent and received (as well as contacts and calendars) over a long period. It is not recommend using mailbox level backups as a disaster recovery method because restoring an entire information store via a Mailbox Level backup is much slower than from an Information Store backup.

The backup agent only supports backing up mailboxes from a single domain. If you would like to back up data from a different domain using an existing sub-account, then you need to delete the backup set and backed up data before you can edit the URL. If you would like to back up from a second domain, create a new sub-account and install the backup agent on the second system.
