If you're asking how to create a multipart/alternative message with
text/plain and text/html sub-parts with Lookout - er, Outlook - , that
is an Outlook question and not a Mailman question.

If you're asking how to pass such a message through Mailman unscathed,
currently (2.1.6) you have to turn off content filtering (or not turn
it on). Content filtering, regardless of what other filtering it does
if any, will collapse any remaining multipart/alternative parts into
just the first remaining sub-part. The next release will include a
list option to not do this. If you need this option now to enable
content filtering, but not collapse multipart/alternative, see
