An obvious solution is "don't quote every previous email in a reply".
It's a ridiculous practice instigated by Microsoft which adds nothing
of value. However that's not always possible to avoid because of
corporate standards.

Are you composing in HTML? That's probably at the root of the problem.
I think Milan has mentioned an improved composer coming soon, so that
may correct the issue. In the meantime, consider writing in plaintext
if possible.
