Backups are retained for 14 days; if a message was deleted from the system 13 days ago, but the email was present for the nightly backup 14 days ago, the message can be restored. This can be done via the control panel by the system administrator.

Individual folders or entire mailboxes can be restored to either the original mailbox or to an alternate mailbox. This allows greater flexibility for email administrators and email users in recovering an important email message.
