SYMPTOMS

When connecting Microsoft Exchange Server X.400 Connector to a remote message transfer agent (MTA) using 1988 mode, you may encounter the following Event ID logged in the Windows NT Event Viewer:

Event ID: 55
Source: MSExchangeMTA
Category: security

The incorrect link option mode was specified by the binding remote entity
/O=org/OU=site_name/CN=CONFIGURATION/CN=CONNECTIONS/CN=remoteMTA ,
association index: 2130. [MTA XFER-IN 22 35] (14)


The connection will fail.

CAUSE

The Event ID indicates that the remote MTA is trying to negotiate a two way alternate link option which is not a valid option for this connection. This setting can be verified and changed in the X.400 Link Options check box selection on the Advancd tab of the X.400 Connector properties page of the Exchange Server Administrator program.

SOLUTION

Disable the two way alternate option from the remote MTA and configure it to use monologue.
