This behavior occurs only when the Exchange Server computer is running an English-language version of Microsoft Windows NT Server. CAUSE ===== MBClean logs on to each mailbox and searches each subfolder for the overdue messages. To generate a report message, it calls the GetProps() function to retrieve the display name of each subfolder. The GetProps() function converts the folder name from Unicode to the native code page of MBClean, which correlates to the version of Windows NT Server. In this case, it is converted to English but not DBCS. RESOLUTION ========== To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, please see the following article in the Microsoft Knowledge Base: Q191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5 Service Pack 3. This problem was first corrected in Exchange Server 5.5 Service Pack 4. MORE INFORMATION ================ The new version of MBClean introduces the following new registry key for the code page of the folder name: DWORD: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeMCA\Parameters\SecondCodePage" NOTE: For example, the value is 936 for Chinese Simplified (CHS). MBClean uses this key instead of the native code page of MBClean itself. If there are several kinds of DBCS clients in a site, you need to group them on different servers and add this registry key with a corresponding value on each server.
