Analysing Exchange Server 2010 Jetstress BLG Files By Hand

Database Maintenance in Exchange Server 2010

If there is one area of Exchange 2010 that was poorly documented and poorly understood it has to be database maintenance.  The problem stemmed from the significant changes that we made in the store for Exchange 2010 and a confusion of terms.
