CDO is not part of the default Outlook installation. You may need to rerun setup and install it.

Thanks your reply. My Outlook is version 11.0 as checked under

It is Outlook, not Outlook express. I have followed Brian instruction.
However, I cannot find cdo or any cdo related file. Something wrong with my
Outlook? I am using Exchange server 2003. I can find the cdo version of the
Exchange server. However, I don't know how to find the cdo version of
Outlook.

I think the OP was saying the CDO's version should be 6.x. Mine, for
example, is 6.5.7233.48. being used with Outlook 2003. CDO is located in
%CommonProgramFIles%\system\msmapi\1033\cdo.dll
