SYMPTOMS
A Microsoft Exchange Inbox rule that forwards mail from a user in Site A to a user in Site B may fail when the sites are not replicating but are connected only via an address space. After carrying out the rule, the Information Store will attempt to submit the message to the Message Transfer Agent (MAT) for delivery, and then the MTA will produce a message similar to the following in the application log:

An error occurred while transferring in message C=US;A= ;P=Organization; L=DMSBLD-960824032321Z-45 because the directory name could not be expanded to an O/R address. An X.400 API Association (XAPIA) unable-to- transfer reason code and unrecognized-OR-name diagnostic code were returned. [MTA SUBMIT 9 73] (14)



CAUSE
When a message is delivered by the MTA to the Information Store, it has the MAPI property PR_ORIGINATOR_* stamped on it. The existing rules code does not exclude the PR_ORIGINATOR_* information and this caused the originator information to be included in the P1 envelope on an autoforwarded message. Because the originator does not exist in the Directory where the message is being forwarded, the MTA generates the NDR.



RESOLUTION
To resolve this problem, obtain the hotfix mentioned below. The rules code was modified to exclude the PR_ORIGINATOR_* information on an autoforwarding rule.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange version 4.0.

This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base:
