java代码如下：
public static void main(String[] args) throws IOException, GeneralSecurityException {
final String username = "*** 因为隐私原因删除电子邮件地址 ***";
final String password = "xxx";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.office365.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
session.setDebug(true);
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(username));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("xxx"));
message.setSubject("Test");
message.setText("HI");
Transport.send(message);
} catch (MessagingException e) {
