Message Text

Process %1 (PID=%2). Recipient object %3 read from %4 failed validation. A data validation exception will be given. Set event logging level for Validation category to Expert to get additional events about each failure.

Explanation

This Error 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 (FCO) if all its attributes contain valid values and these values are consistent with other attributes.

User Action

To determine which attributes or properties contain invalid values, increase diagnostic logging. 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.

After the diagnostic logging level has been set to 5 (which is Maximum), review other Warning and Error 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, Lowest.
