TITLE   :XFOR: MIME Inbound Mail Failure on ISO-2022-JP Character Set
PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0,5.0
OPER/SYS:
KEYWORDS:kbusage

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, versions 4.0, 5.0 
-------------------------------------------------------------------------------

SUMMARY
=======

After you upgrade Microsoft Exchange Server version 4.0 to Service Pack 2 (SP2),
SMTP messages that use ISO-2022-JP as the character set might cause the
following error:

   From: System Administrator
   Subject: Notification: Inbound Mail Failure - Message could not be processed

The notice will include the original message as an attachment. The message might
have been sent in English but it will have originated from a Japanese based
client. The administrator can forward the message on to the original recipient
with no further difficulty.

In order to prevent this error, you will need to install the Japanese Code Page
on the NT server where the Microsoft Exchange Internet Mail Connector is
running.

NOTE: The Japanese Code Page can be obtained from the Japanese version of Windows
NT 3.51 CDROM. Also, it can be obtained from the Microsoft Developer Network
CDs.

MORE INFORMATION
================

The SP2 upgrade includes Double-byte Character Set (DBCS) Support. This means
that all versions of Microsoft Exchange Server accept and can administer all
other versions, including full support of Far East and Eastern European
character sets. However, if the associated code page for that language is not
installed on the server, messages from those other versions will result in the
inbound failure error.


For additional information on how to add code pages for languages not included in
this list, please see the following article in the Microsoft Knowledge Base:

   Q151701

A brief example showing the use of these steps is included here for clarification
only.

The following example would be for the ANSI code page adding the Japanese
character set (932):

1. Copy the code page file to the Winnt/System32 directory. In other words, copy
   C_932.nls to c:\winnt\system32.

2. Start the registry editor, Regedt32.exe.

3. Add a new value for Japanese under the key:

   \\ HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Nls\CodePage
   Value Name: 932
   Data Type: REG_SZ
   String: c_932.nls

4. Add a new value for the Locale Specific key:

   \\ HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Nls\Language
   Value Name: 0411
   Data Type: REG_SZ
   String: l_intl.nls
