Specifically, increase the diagnostic logging level on the Validation counter of the MSExchange ADAccess performance object to High. For detailed information about how to increase logging, see Manage Diagnostic Logging Levels.

  2. Review the additional MSExchangeADAccess events in the Application log to determine which attributes or properties contain invalid values.
