带有附件的Java邮件在smtp.office365.com，港口：587

Question

我无法使用SMTP.Office365.com（无附件工作）发送带有附件的电子邮件，而是通过Gmail的工作方式发送电子邮件。

javax.mail.MessagingException: Could not connect to SMTP host: smtp.office365.com, port: 587;
  nested exception is:
    javax.net.ssl.SSLException: Unsupported or unrecognized SSL message
    at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1961)
    at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:654)
    at javax.mail.Service.connect(Service.java:317)
    at javax.mail.Service.connect(Service.java:176)
    at javax.mail.Service.connect(Service.java:125)
    at javax.mail.Transport.send0(Transport.java:253)
    at javax.mail.Transport.send(Transport.java:124)

具有以下配置

Properties props = new Properties();

props.put("mail.smtp.host", "smtp.office365.com");
props.put("mail.smtp.port", "587");        

props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.socketFactory.port", "587");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.ssl.protocols","TLSv1.2");
props.put("mail.smtp.socketFactory.fallback", "false");
