        message.subject = "Test message";
        message.body = ItemBody("<html><body>Message body</body></html>", ContentType::Html);
        message.to_recipients.push_back(EmailAddress("elon@independentsoft.com"));
        message.to_recipients.push_back(EmailAddress("pia@independentsoft.com"));

        Message createdMessage = sync_wait(client.create_message(message, UserId("info@independentsoft.onmicrosoft.com")));
