TITLE   :XFOR: DBCS Attachment File Name Not Encoded If Using UUENCODE
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.0,5.5
OPER/SYS:
KEYWORDS:exc55sp2fix exc5 exc55

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

 - Microsoft Exchange Server, versions 5.0, 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

The Microsoft Exchange Internet Mail Service is configured to use the UUENCODE
encoding method, and the message is correctly encoded in the configured
character set. However, a double-byte character set (DBCS) attachment file name
is always encoded with Shift-JIS, even if JIS or EUC is specified as the
character set translation.

CAUSE
=====

Exchange 4.0 Internet Mail was used to encode all file names into the configured
character set. The behavior was changed for Exchange 5.0 and 5.5, due to
interoperability problems with other messaging clients. Those messaging clients
apparently have changed their behavior, so a hotfix has been created for 5.0 and
5.5 that change them to behave like 4.0.


RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:

   Q191014 XGEN: How to Obtain the Latest Exchange Server 5.5 Service Pack
