Just to add to what Sue mentioned, you are not allowed to deploy CDO
yourself, you have to download it from the Web distribution on the MS Web
site. You can of course write code to do that. I'd definitely agree with Sue
about CDO being dead end technology.

Regarding compatibility, Outlook object model code *is* compatible between
versions, as long as you use only objects, properties, methods, and events
from the oldest version of Outlook you want to support. You certainly
can't
expect new features introduced in the latest version to be back-ported to
older versions.

The CDO 1.21 object model is an entirely different matter. It's a dead end
technology with no new features added in years and probably no one
remaining
at Microsoft who completely understands it. Now that the bulk of its
functionality is available in native Outlook objects, Microsoft has no
reason
to include it with Outlook and every reason to try to deter people from
using
it so they can get rid of it completely at some point.
