Description
Administrator responsibilities include the ability to react to unplanned maintenance tasks or emergency situations that may require Public Folder Store data manipulation. Occasionally, there may be a need to start the server with "unmounted" data stores if manual maintenance is being performed on them. Failure to uncheck the "do not mount on startup" condition will result in unavailability of Public Folder services. Correct configuration of this control will prevent unplanned outages due to being enabled. When maintenance is being performed, care should be taken to clear the check box task completion so public folder stores are available to users (unmounted public folder stores are not available to users).
