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. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

1. Start Registry Editor (Regedt32.exe).
2. Locate the following key in the registry:

        HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeCCMC
        \Parameters
   						

   NOTE: The above registry key is one path; it has been wrapped for readability.
3. On the Edit menu, click Add Value, and then add the following registry value:

         Value Name: Use long filename
         Data Type:  REG_DWORD
         Value:      1
   						

   NOTE: If the registry value is set to 1, the Exchange Connector for Lotus cc:Mail will send the attachment with a long file name to the cc:Mail postoffice. If the registry value is set to 0 or does not exist, the cc:Mail Connector will send the attachment with an 8.3 format file name to the cc:Mail postoffice.
4. Quit Registry Editor.
