Problemas com configuração de conta outlook365 utilizando javamail.

Olá, Estudando sobre a classe Javamail, implementei um programa que envia e-mails utilizando uma conta outlook365, porém, após configurar e executar o programa ocorre uma exception (SocketException), gostaria de saber o que estou configurando de errado e como posso resolver isso? Segue abaixo classe e a pilha de erros.

                return new PasswordAuthentication(CONTA_PADRAO, SENHA_CONTA_PADRAO);
            }

        });

            message.setText(messageContent);
            session.setDebug(true);
            message.setSentDate(new Date());
            Transport.send(message);
        } catch (final MessagingException ex) {

        config.put("mail.smtp.port", PORTA_SERVIDOR_SMTP);
        return config;
    }

    public static void main(final String[] args) {
        new SendEmailOffice365().sendEmail();
    }

}
