A message that contains one byte Kana stays in the Directory Lookup queue in Exchange Server 2003 when the message is sent by using OWA

When you use Outlook Web access (OWA) to send a message that contains one byte Kana, the message stays in the Directory Lookup queue. The message cannot be delivered successfully.

This problem occurs if the following conditions are true:

• You enable message archiving for one or mailbox stores that have target mailboxes on a Microsoft Exchange Server 2003 server.
• You send the message from a mailbox that is located on the target stores.

This problem occurs when a message contains half-width Kana in numeric character reference (NCR) shape. A conversion problem exists for characters in NCR shape.

An NCR is a common markup construct that is used in Standard Generalized Markup Language (SGML) and in other SGML-based markup languages, such as HTML and XML. An NCR consists of a short sequence of characters that represent a single character from the Unicode Universal Character Set (UCS). NCRs are typically used to represent characters that cannot be directly encoded in a particular document. When a markup-aware reader interprets the document, each NCR is treated as if the NCR were the character that the NCR represents.
