Messages sent using Thunderbird but said not to be received by the
addressee.


Make sure Thunderbird is not in 'off-line' mode?

If you see sent items remaining in the Outbox ...
I don't think I've met "offline mode".
The messages have found their way to my sent file ok.

Examine the items in the Sent folder carefully.

OK

Do the items have a "newsgroup:" line in them ?

No. Just my mail address.

Thunderbird is notorious for mixing up reply and followup
and emails end up going to newsgroups or vice versa.

Using the message in the Sent, see if you can figure
out what subsystem it was headed to.

Beyond my competence! Straight forward mail address that has worked
before.

Because this was a commercial enquiry, I wonder if mail is being
re-directed from their office to a home computer and someone didn't do
the necessary?
