SYMPTOMS
You use Microsoft Outlook Web Access (OWA) to open an e-mail message that has an attachment that contains a double-byte character set (DBCS). If you click the attachment, and then click Save to save the attachment, the attachment file name in the File name box is a random string of characters and not the original name of the file.

NOTE: DBCS is a character set that uses 16 bits to represent a character. DBCS is used in Japan, Korea, Taiwan (Traditional Chinese), China (Simplified Chinese), and Hong Kong (Simplified Chinese).



CAUSE
This problem occurs because of grammar limitations that are inherent in Request for Comments (RFC) 1521. RFC 1521 grammar limitations currently restrict parameter values and as a result, Content-Disposition file names, to US-ASCII. For any non-US-ASCII character value to be passed, the value must be enclosed in quotation marks. For additional information, see RFC 1521:

RFC 1521



STATUS
Microsoft has confirmed that this is a problem in Exchange 2000.



MORE INFORMATION
RFC 1521 describes a mechanism to represent textual body parts, which are coded in various character sets, and methods to encode these body parts as sequences of printable ASCII characters. For additional information, see the &quot;The Content-Transfer-Encoding Header Field&quot; section in RFC 1521.
