Description
E-mail system availability depends in part on best practices strategies for setting tuning configurations. Unauthorized or accidental restoration of public folder data risks data loss or corruption. This setting controls whether the public folder store can be overwritten by a restore from 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 afterwards. During production windows, this setting must be disabled.
