XADM: Err Msg: Unable to Initialize, Windows Reports Error 1815

• Microsoft Exchange Server, version 5.0

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SYMPTOMS

If you use the Properties command on the Exchange menu in User Manager for Domains to modify the properties of a mailbox, and then attempt to perform a directory import from the Microsoft Exchange Administrator program, you may receive the following error message:

   Unable to initialize because Windows reports error 1815.

CAUSE

When you modify the properties for a mailbox from User Manager for Domains, the default Microsoft Exchange language ID is initialized. The language ID should be obtained from the User Manager for Domains add-on that is installed with Microsoft Exchange Server (Mailumx.dll), but may be obtained from User Manager for Domains instead. If you are running the U.S. version of Microsoft Exchange Server and a DBCS version of Windows NT Server, this may cause the language ID to be initialized incorrectly. When this occurs, you are unable to perform directory imports from the Microsoft Exchange Administrator program.

WORKAROUND

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

To work around this problem, verify that the default Microsoft Exchange language ID is correct before you perform the directory import. To do so, follow these steps:

1. Start Registry Editor (Regedt32.exe or Regedit.exe as appropriate for your version of Windows NT).

2. Locate the following key in the registry:

         HKEY_CURRENT_USER\Software\Microsoft\Exchange\MSExchangeAdminCommon
   

3. Verify that the following value exists under this registry key:

         Value Name: AdminLangID
         Data Type:  REG_DWORD
         Value:      0x009 (hexidecimal)
   
      If this registry value is not assigned a value of 0x009, modify the
      registry value and assign it this value. Note that this value is only
      appropriate if you are using the U.S. version of Microsoft Exchange
      Server.
   
   

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem was corrected in Microsoft Exchange Server version 5.5.
