springでのメール送信に失敗

いつもお世話になっております。

今回、springBootを使ってoutlookのメールを送れるメールフォームを作成しようと思い下記の記事を参考に進めていました。↓
https://reasonable-code.com/spring-boot-mail/#i-3

記事通りにやったところgmailの送信は成功したのですがoutlookに当てはめてみるとエラーが起きました。

エラーコードを見ると認証に失敗しましたとあるのでパスワード周りが怪しいそうです。
しかし、パスワードが正しいのは確認したので、パスワードとは別に認証（二段階認証など）が必要なのでしょうか？
もしくはoutlookの場合は別に設定する項目があるのでしょうか？

実行クラス

package com.example.demo.trySpring;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

@SpringBootApplication
public class DemoApplication implements CommandLineRunner {

	public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    private final MailSender mailSender;

    public DemoApplication(MailSender mailSender) {
        this.mailSender = mailSender;
    }

    @Override
    public void run(String... args) {

        SimpleMailMessage msg = new SimpleMailMessage();
        msg.setTo("送信先メールアドレス1");
        msg.setCc("送信先メールアドレス1");
        msg.setBcc("送信先メールアドレス1");
        msg.setSubject("件名");
        msg.setText("本文");

        // メール送信
        mailSender.send(msg);
    }

}

application.properties

spring.mail.host=smtp.office365.com
spring.mail.port=587
spring.mail.username=送信元メールアドレス
spring.mail.password=outlookパスワード
spring.mail.properties.mail.smtp.auth=true
