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:

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