SYMPTOMS
When you use Exchange 2000 Server, non-delivery reports (NDR) or delivery receipts may not be sent and may accumulate in the Messages awaiting directory lookup queue. However, messages that are correctly addressed are delivered to mailboxes, and outgoing messages are sent successfully.

When Field Engineering is enabled, the following events are reported in the application event log:

Event Type: Warning

Event Source: MSExchangeTransport

Event Category: (2)

Event ID: 6004

Description: The categorizer is unable to categorize messages due to a retryable error. A retryable categorizer error occurred.

Event Type: Warning

Event Source: MSExchangeTransport

Event Category: (2)

Event ID: 9003

Description: Categorizer is temporarily unable to process a message.

CAUSE
This issue can occur if a front-end server that is running Exchange 2000 has an SMTP Connector installed, but the information store is not running.



RESOLUTION
To resolve this issue, start the information store on the server, then create a mailbox store and mount it.



WORKAROUND
To work around this issue, install the SMTP Connector on the back-end server instead.



MORE INFORMATION
For more information, consult the Exchange 2000 Front-end and Back-end Topology white paper that is located at the following Microsoft Web site:

http://www.microsoft.com/exchange/techinfo/deployment/2000/E2KFrontBack.asp

NOTE: This white paper states that a front-end server should not be running an information store. However, the white paper describes a front-end server that does not have an SMTP Connector installed on it.
