Ok, my bad... Missed the -crlf option because SMTP requires CRLF line endings. STARTTLS works.
So actual conclusion: outlook.office365.com SMTP: Plain SSL on Port 465 not accessible. STARTLS on 587 (and 25) works! IMAP: STARTLS advertised but BROKEN on port 143 since 2 days. Plain SSL on Port 993 works!
