SYMPTOMS
If you have configured the Exchange Server message transfer agent (MTA) to map between SMTP addresses and X.400 addresses according to the following Microsoft Knowledge Base article:

238507 XCON: Exchange Server Message Transfer Agent MIXER Mapping Tables

the subdomains of the SMTP address may not be mapped to organizational unit (OU) attributes in the X.400 O/R address.

For example, the following entry in the Mcgam.in.txt file maps "eur.fr" to "C=FR;A=ADMD;P=PRMD":

eur.fr#prmd$PRMD.admd$ADMD.c$FR#

A message that is addressed to user@dept.area.eur.fr should then be converted to an X.400 message that is addressed to C=FR;A=ADMD;P=PRMD;O=area;OU1=dept, but the actual mapping is to C=FR;A=ADMD;P=PRMD;O=area. No OUs are mapped.



CAUSE
This issue can occur because the Exchange Server MTA contains a logic error that causes the generated OU values to be overwritten.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5 Service Pack 3. This problem was first corrected in Exchange Server 5.5 Service Pack 4.
