Question

此代码将消息发送到附加了ics存档的Outlook帐户，但是Outlook无法将其识别为事件，也不会在预览中显示。使用Gmail不会有任何问题。它很好地显示了预览，但是Outlook似乎不兼容。我正在使用ical4j libary版本3.0.6。有人可以帮我找到问题吗？谢谢

        final String username = "example@gmail.com";
        final String password = "pass";
        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");

        try {
            Session session = Session.getInstance(props, new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(username, password);
                }
            });

            // Define message
            MimeMessage message = new MimeMessage(session);
            message.addHeaderLine("method=REQUEST");
            message.addHeaderLine("charset=UTF-8");
