    Additional Information

    • When installed on SQL Express DisableTrackingCutoffDatabaseSizeMB is set to 3700 by default.
    • To avoid this in the future, consider upgrading the SQL Express server to SQL Standard (or higher) to avoid database size limitations:
      • DisableTrackingCutoffDatabaseSizeMB can be set to 0 after upgrading to SQL Standard (or higher).
      • DisableTrackingCutoffDatabaseSizeMB is default set to 0 when initially installed on SQL Standard (or higher).
