Make sure that you install the same service pack that your exchange server is running as well as hotfixes to the machine where you are installing the ESM (as well as BES).
Once that is done, extract cdo.dll from the LAST service pack / hotfix that you've applied, copy it to the \exchsvr\bin\ directory and register the DLL. The service packs and hotfixes dont install & register this file on a machine where ESM is installed, but not the entire exchange server.
