JavaMail - 无法使用 SSL 发送邮件

Question

我正在尝试通过使用以 office365 作为主机的 JavaMail 启用 SSL 来发送邮件。当我将主机用作smtp.gmail.com 时，它工作正常但不适用于smtp.office365.com 以下是我的方法：

public class SendMail
{

     public static void main(String args[]){
        String username = "abc@xyz.com";
        String password = "abc123";
        Properties properties = new Properties();
        properties.put("mail.smtp.host", "smtp.office365.com");
        properties.put("mail.smtp.socketFactory.port",995);
        properties.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
        properties.put("mail.smtp.auth", "true");
        properties.put("mail.smtp.ssl.enable", "true");

        Session session = null;

        if (authenticationRequired) {
          session = Session.getInstance(properties,
              new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(userName,password);
                }
              });
        }else{
             session = Session.getDefaultInstance(properties);  
       }
       try{
            MimeMessage message = new MimeMessage(session);
            message.setFrom(new InternetAddress(username));
            message.setSubject("Test mail");
            message.setContent("Test Mail", "text/html");
            message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(john@gmail.com));

            Transport transport = session.getTransport("smtp");
            transport.connect();
            transport.sendMessage(message,message.getAllRecipients());
       }catch(Exception e){
          e.printStack();
       }
     }
  }

它抛出异常为 - Could not connect to SMTP host: smtp.office365.com, port: 995 response: -1。我也尝试将端口设置为993，但这也不起作用。请帮帮我。 Other approaches are also welcome

如您所说，使用 gmail 是否将 gmail 的证书导入您的密钥库？
