Have a look at:

   http://kb.mozillazine.org/MAPI_Support

which explains that TB (like OE) only supports "Simple MAPI". There's
a whole confusion of terminology around this area, but I'm afraid that
the bottom line is: the only client which really supports CDO, ie MAPI.Session
is the full Outlook client. It's just about possible to use CDO without
installing Outlook (by installing some standalone package whose name
escapes me) but that still only gives you access to Exchange, not to
whatever interface TB exposes.
