Disagree!
This message was only send to people using 'To' and 'Cc', and still
got messed up with =20 and other things.

Disagree all you want. Up to this point, no one has ever presented evidence
for the problem under any condition except what I've described. Before I
could conclude that what you're seeing is a result of the same issue, I'd
have to know more about it. The message you included appears to have come
from you, not received by you. That means one of the other people (in the
To or Cc) must have received it any it is they who might have seen the
problem. Moreover, I see no evidence that there's any "undisclosed
recipients" in the example you included, yet in your initial post you said
"Outlook changes it into 'undisclosed-recipients'".
