Exchange 2013 Managed Availability
This tips describes the new Managed Availability feature present in Exchange 2013.
In Exchange 2013, native, built-in monitoring and recovery actions are included in a feature called Managed Availability. Managed Availability is the integration of built-in, active monitoring and the Exchange
