SYMPTOMS
When a client sends a message, they receive an error message from the MSExchangeMTA that states:

An error occurred while transferring in a message C= ;A=< >; P=;L= because the Directory could not be expanded to an O/R address.

Event ID 178.



CAUSE
The account designated as the Microsoft Exchange Internet Mail Connector (IMC) administrator is missing an X400 address.



RESOLUTION
You need to either give the administrator's account an X400 address or assign a different account as the IMC administrator. Adding an X400 address is done on the E-Mail Addresses tab of the account's property page. Assigning a different administrator account is done by clicking the Change button on the IMC's property page.



MORE INFORMATION
If the IMC service is stopped with the administrator's X400 address missing, it will not restart with a Dr. Watson and a 1067 error.
