| Description |
|---|
| Email system availability depends in part on best practice strategies for setting tuning configurations. Unauthorized or accidental restoration of mailbox data risks data loss or corruption. This setting controls whether the mailbox store can be overwritten by a backup, which will cause loss of all information added after the backup was created. It should only be enabled during maintenance windows or following an outage (immediately before a restore is to be made), and cleared again immediately afterward. During production windows, this feature must be disabled. |
