A description of the support of the localized Outlook client in Exchange 2000 Server

This article describes the support of the localized Microsoft Outlook client in Microsoft Exchange 2000 Server.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
In Microsoft Exchange Server 5.5, you had to add a code page to Microsoft Windows NT Server and locales to Exchange Server to enable the support of multiple languages. In Exchange 2000, however, this situation has changed.

In a multiple language or localized environment, some user display names may be in English and others may be in localized languages, such as, German, French, or Chinese. When an Outlook client views the global address book, the display names may be not sorted correctly.

Exchange 2000 does not have an independent directory service, and Exchange 2000 is closely integrated with Microsoft Windows 2000 Active Directory. When a Microsoft Outlook 2000 client attempts to obtain the global address book, the client directly contacts the preferred global catalog. For an earlier-version Outlook client, Exchange 2000 server can obtain the global address book from global catalog and forward it to the client.

To have the global address book sorted correctly, you must configure Windows 2000 domain controller and global catalog to support the languages that are going to be used. To do so, you must perform the following steps on all global catalogs and domain controllers:

1. In Control Panel, double-click Regional Options.
2. On the General tab, under the Language settings for the system section, click to select the check box for the language that is going to be supported.
3. Restart your computer for the changes to take affect.
4. Start Registry Editor (Regedit.exe).
5. Click to expand the following subkey in the registry:
   HKEY_LOCAL_MACHINE/Software/Microsoft/Ntds/Language
6. Right-click Language, point to New, and then click DWORD Value. Enter a name for the string, and then press ENTER.
7. Right-click the DWORD value that you just created, and then click Modify. In Value data, enter the value of the locale identification (ID) that you want to support.
8. Restart the global catalogs and domain controllers.
