This is little more than a guess, but it may be the difference between
SMTP STARTTLS and "ssmtp", the kind of thing Exim can do when wrapped in
an stunnel (though remember to require SMTP in this case).

You could try the stunnel listening on port 465. Or maybe try tcp/587
which is the "submission" port. Maybe, just maybe, Outlook will talk
"real" SMTP to 587.
