XFOR: Directory Replication Fails over Internet Mail Service

• Microsoft Exchange Server, versions 5.0, 5.5

SYMPTOMS

When you try to perform directory replication between two Microsoft Exchange Server computers that are connected by an Internet Mail Service, directory replication may fail. The directory replication messages are received by the Internet Mail Service, but directory replication does not occur.

CAUSE

This problem can occur when the directory replication messages received by the Internet Mail Service have an address type of MSXCHNGE instead of EX. When this happens, the Internet Mail Service may be unable to convert the address to a Simple Mail Transfer Protocol (SMTP) address. The address is also not recognized as an Exchange address. Therefore, the Internet Mail Service is unable to deliver the message.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0.

A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem.
