XADM: Messages Not Rerouted Between Two X.400 Connectors in Same Site

ID: Q184662

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

In this scenario, an Exchange site has two servers, and each of them has an X.400 Connector with the same address space but different costs. For example:

ServerA with an address space of X.400:<nothing> and a cost of 1
ServerB with an address space of X.400:<nothing> and a cost of 90

Messages created on a mailbox on ServerB and addressed to an X.400 recipient are routed this way:

B -> A -> X.400 Connector

If ServerA goes down, then messages created on a mailbox on ServerB and addressed to an X.400 recipient are not locally rerouted to ServerB's X.400 Connector but remain indefinitely in ServerB's MTA queue to ServerA.

NOTE: This happens only with Custom recipients. Messages sent to a one off address are correctly rerouted.

RESOLUTION

To work around this problem, a manual intervention (modification of the connector cost, recalculation of the routing table) is required to activate the rerouting.

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
