Hello Damon, Here is a part of a KB article about it (sorry I do not know the KB ID), I had the same problem last year and it took me a while to find it. Remeber that you need to do this on all DC/GC:s that the asian clients can connect to: ----------------------------------------------------------------------- Configuring Windows 2000 Domain Controller and Global Catalog to Support International Clients For Exchange Server to support multilingual Outlook clients two things need to be done. First, the Windows 2000 server where the global catalog is installed must have language support installed. To install language support, in the Regional Options control panel, click the General tab, and then under Language settings for your system, select the languages that you want to support. To support multilingual Outlook clients, you must also add a registry key to support international sorting in Active Directory for MAPI clients. By default, Active Directory will only support English sort orders. A sort order can be added by adding the locale ID values to a registry key on the Windows 2000 server where the global catalog is installed. To set the registry key on the server: On the Start menu, click Run. In Open, type regedit. Locate the following key: HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Ntds/Language Right-click Language, point to New, and then click String Value. Type a name for the string, and then press ENTER. Right-click the string value you just created, and then click Modify. In Value data, type the value of the locale ID that you want to support. ----------------------------------------------------------------------- Best regards Mikael Bergqvist Dialog Semiconductor IT Department S:t Lars väg 46 Ideon Park S-222 70 Lund Sweden Phone: +46 46 2702 144 Mobile: +46 708 742002 Email:mikael.bergqvist@xxxxxxxxxxx
