Thanks Brian,
but I don't understand the meaning of the option.
"...save replies with original message" is NOT ticked but when I reply
to a message I always have the original message included.
Otherwise it would quite laborious to follow a thread.

don't apply to other rules and have them copied to Sent items.
Outlook needs an overhaul!

That's how Outlook has always done what you wish to accomplish. I doubt if
MS will change it.

Investigate, as well, the "In folders other than the Inbox, save replies
with original messages" option. This may save you from having to create so
many rules.
