SYMPTOMS
When an e-mail message that contains a recipient's display name in double-byte character set (DBCS) is sent to an Exchange Server user through Internet Mail Connector, the recipient's display name may be corrupted.



CAUSE
Internet Mail Service incorrectly removes backslash characters (\) from the string of the display name in the To field. In some DBCS character sets, a backslash character does not have a specific meaning but is part of the DBCS character set. If the character is removed, the string is corrupted.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help to prevent any unauthorized changes to the file.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 4.



MORE INFORMATION
The new version of Store.exe uses a new registry key that turns on/off the checking for the quoted pairs. This should resolve the issue without adding the code page overhead.

The registry key is shown below:

DWORD:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIs\ParametersSystem\InternetContent\BackSlashIsEscape

When this value is set to 1, all checks for the backslash character are ignored (so all backslash characters are kept).
