The categorizer configuration is invalid.

This Error event indicates that the categorizer configuration is invalid.

Every message that is sent or received by a Microsoft Exchange Server 2007 Hub Transport server or Edge Transport server must be categorized before it can be routed and delivered. On an Edge Transport server, categorization is a short process in which the message is put directly in the delivery queue. On a Hub Transport server, the categorizer performs the following steps:

  • Recipient resolution, which includes top-level addressing, expansion, and bifurcation

  • Routing resolution

  • Content conversion

For more information, see Transport Architecture.

To resolve this error, do one or more of the following:

  • Restart the Microsoft Exchange Transport service.

  • Increase the diagnostic logging level on the Categorizer counter of the MSExchangeTransport performance object. You can increase logging by running the following Exchange Management Shell command:

    Set-EventLogLevel "MSExchangeTransport\Categorizer" -Level High

    For more information about how to increase logging, see Changing Process Logging Levels.

  • Review other related Error and Warning events in the Application log. These related events may help you find the root cause of this error.

    Important   After you have finished troubleshooting this issue, return logging to the default level by running the following command:

    Set-EventLogLevel "MSExchangeTransport\Categorizer" -Level Lowest

  • If the recommended steps do not resolve this error, contact Microsoft Customer Support Services. For more information about how to contact support, visit the Microsoft Help and Support Web site.
