SYMPTOMS
When you attempt to send e-mail to a public folder in a mixed Exchange Server environment (Exchange 2000 Server and Exchange Server 5.5), a non-delivery report (NDR) occurs on the Exchange Server 5.5 computer. The following events are issued by the Exchange Server 5.5 computer that receives the e-mail message:

Event Type: Information

Event Source: MSExchangeMTA

Event Category: X.400 Service

Event ID: 270

Description:

A permanent error has occurred with Entity /O=ORG/OU=SITE/CN=CONFIGURATION/CN=SERVERS/CN=SERVER_NAME/CN=MICROSOFT PUBLIC MDB. Entity is a Message Object is a Normal Priority Message.

Object: #######. Message ID: C=us;A= ;P=Company;L=Server_Name###### Content length: ####, External Trace information (first ### bytes) = ##### PDU dump reference ###

Event Type: Warning

Event Source: MSExchangeMTA

Event Category: X.400 Service

Event ID: 290

Description:

A non-delivery report (reason code transfer-failure and diagnostic code Omit any diagnostic code) is being generated for message C=us;A= ;P=ORG;L=Server_Name#####. It was originally destined for DN: ; (recipient number #), and was to be redirected to.



CAUSE
This behavior occurs if both of the following conditions are true:
 * No Exchange 2000 Server computers in the Routing or Admin group have a public folder store for the Messaging Application Programming Interface (MAPI) Public Folder tree.

-and-
 * No Exchange Server 5.5 computers in the Routing or Admin group have replicas of the folder being e-mailed.

If the Exchange Server 5.5 information store receives the e-mail and cannot &quot;reach&quot; a replica of the e-mailed folder, it issues an error message to the message transfer agent (MTA). The MTA then issues an NDR.



RESOLUTION
To resolve this issue, use any of the following methods:
 * Add a MAPI public folder store to the Exchange 2000 Server computer in the Routing group or Admin group.

-or-
 * Add a replica of the folder in question to an Exchange Server 5.5 computer in that site.

-or-
 * Set up an affinity from the Exchange Server 5.5 site to an Exchange Server 5.5 site that contains a replica of the e-mailed public folder.



STATUS
This behavior is by design.
