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:<DN of public
  folder>; (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
"reach" 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.
