SYMPTOMS
Consider the following scenario. A mailbox that is located on a Microsoft Exchange Server 2007 server has a server-side rule that forwards e-mail messages to target recipients. The original e-mail message is included in the body of the forwarded message. In this scenario, the recipients experience the following symptoms:
 * If the original e-mail message contains double-byte character set (DBCS) characters in the subject line, the DBCS characters are converted into question marks in the forwarded e-mail message. This is also true if the original message contains DBCS characters in the display name of the recipient.
 * If the sender of the original e-mail message has a display name that contains DBCS characters, the sender's display name in the forwarded e-mail message is changed to the following legacyExchangeDN attribute:

/o= /ou= /cn=Recipients/cn=



CAUSE
This problem occurs because Exchange 2007 uses English as the code page when Exchange 2007 processes the server-side rule that forwards e-mail messages to target recipients. Exchange does not use the code page of an e-mail message to process the rule. The header information for the original e-mail message is incorrect if DBCS characters are included.



RESOLUTION
To resolve this problem, download and install Update Rollup 3 for Exchange 2007.

WORKAROUND
To work around this problem, use the Forward it to people or distribution list as an attachment rule so that the original message will be an attachment of the forwarded message.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
