Читать и написать электронное письмо с помощью Microsoft Graph API Java ⇐ JAVA

[Anonymous]

Я хочу прочитать и отправить электронную почту с помощью Microsoft Graph API. Я пытался использовать DeviceCodecredentials, и они работают нормально, но я хочу прочитать электронные письма без какого -либо взаимодействия с пользователем в бэкэнде. Используя DeviceCodecredentials, он просит меня входить в систему, используя мой идентификатор электронной почты и ввести предоставленный код.
ниже i код, который я написал с помощью Clientsecretcredentials, которые дают мне ошибку ниже. < /P>
