A new feature is available to automatically stop the Microsoft Exchange Information Store service when a time-out is detected in an Exchange Server 2007 SP3 environment

• If you configure the recovery option of the Microsoft Exchange Information Store service to Restart the Service, the Microsoft Exchange Information Store service starts automatically after a crash.
