Explanation
This Warning event indicates that the recipient object specified in the event description is in an inconsistent state. An inconsistent state means that one or more attributes of the specified recipient object contain corrupted or invalid values. A recipient object is considered a Fully Consistent object if the following conditions are true:
All its attributes contain valid values.
These values are consistent with other attributes.
This event indicates that the specified recipient object is inconsistent and will be ignored.
User Action
To resolve this warning, do the following:
Increase diagnostic logging so that you can determine which attributes or properties contain invalid values. Specifically, increase the diagnostic logging level on the Validation counter of the MSExchangeADAccess performance object. You can increase logging by running the following Exchange Management Shell cmdlet: Set-EventLogLevel MSExchangeADAccess\Validation -Level High. For detailed information about increasing logging, see How to Change Logging Levels for Exchange Processes.
Review the additional MSExchangeADAccess events in the Application log to determine which attributes or properties contain invalid values.
Important After you have completed troubleshooting this issue, return logging to the default level by running the following cmdlet: Set-EventLogLevel MSExchangeADAccess\Validation -Level Lowest.
