Delivery status notification messages in Exchange 2000 Server do not appear correctly for some recipients after you configure the SMTP virtual server to use the French language

After you configure the LanguageID entry of the Simple Mail Transfer Protocol (SMTP) virtual server instance to use the French-language code page, when Microsoft Exchange 2000 Server sends a delivery status notification message such as a non-delivery report (NDR) or a delivery report, the text in the delivery status notification message may not appear correctly for some recipients.

This problem occurs because the Exchange 2000 Server component Phatq.dll generates delivery status notification messages that are encoded in the Unicode UTF-7 character set. Because some client programs or Web-based messaging systems cannot decode the Unicode UTF-7 character set, the delivery status notification message does not appear correctly for that recipient.

After you install the hotfix

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

After you install the hotfix that is described in this article, you must modify the value in the Windows registry. Modify the value to enable Exchange 2000 Server to encode existing languages under different character sets. To do so, follow these steps:

1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SMTPSVC\Queuing
   If the
   Queuing
   key does not exist, create it. To do so, follow these steps:
   1. Right-click SMTPSVC, point to New, and then click Key.
   2. Name the new key Queuing.
3. Right-click Queuing, point to New, and then click DWORD Value.
4. Name the new value DSNCodepage.
5. Right-click DSNCodepage, and then click Modify.
6. In the Value data box, type the code page value that you want to assign to DSNCodepage. For example, type 000004e4, and then click OK.
   
   Note 000004e4 hexadecimal corresponds to 1252 decimal (Latin I (Windows 1252)).
7. Right-click Queuing, point to New, and then click String Value.
8. Name the new value DSNCharset.
9. Right-click DSNCharset, and then click Modify.
10. In the Value data box, type the character set that you want to assign to DSNCharset, and then click OK. For example, type iso-8859-1.
    
    Note ISO-8859-1 corresponds to Western European (ISO-8859-1).
11. Quit Registry Editor.

If you change the language settings of the Delivery Status Notification (DSN) to English, the POP3 client that cannot decode the Unicode UTF-7 character set will be able to read the DSN.

To change the language settings of the Delivery Status Notification (DSN) to English, follow these steps:

1. Stop the SMTP service on the computer that is running Exchange 2000 Server.
2. At a command prompt, run the following command:
   cscript.exe c:\inetpub\adminscripts\adsutil.vbs set smtpsvc/SmtpDSNLanguageID 1033
   Note For this command, we assume that Microsoft Windows 2000 Server is installed on drive C.
3. Restart the SMTP service.

Note To set the DSN language settings back to their original settings, follow these steps:

1. Stop the SMTP service on the computer that is running Exchange 2000 Server.
2. At a command prompt, run the following command:
   cscript.exe c:\inetpub\adminscripts\adsutil.vbs set smtpsvc/SmtpDSNLanguageID 1036
   Note For this command, we assume that Microsoft Windows 2000 Server is installed on drive C.
3. Restart the SMTP service.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

The registry value is a string value that indicates the character set that Exchange 2000 Server stamps the delivery status notification message as. The registry value contains a DWORD value that determines the code page that Exchange 2000 Server tries to convert the Unicode to. These registry changes only permit Exchange Server to encode existing languages under different character sets. These registry changes do not add additional language support to Exchange Server. If you specify an unsupported character set and code page, the delivery status notification that is generated does not appear correctly.

For more information about how to edit the LanguageID entry of the SMTP virtual server, click the following article number to view the article in the Microsoft Knowledge Base: Note In this Microsoft Knowledge Base article, a smtpdsnlanguageid value of 1033 (English) is used. The smtpdsnlanguageid value for the French language is 1036.
