Ошибка при отправке электронной почты как пользователя из Microsoft Graph с помощью функций привязки Azure дает UnknownError

Question

У меня есть функция Azure 2.0, настроенная для использования привязки Microsoft Graph, чтобы я мог отправлять почту от пользователя, когда он нажимает на функцию.Я использую библиотеки классов C # с кодом ниже в конце этого сообщения.

Это прекрасно работает в одном клиенте, где домен (abc.onmicrosoft.com), с которым я вызываю функцию, совпадает сПользователь Я вошел как.Однако в другом клиенте (def.onmicrosoft.com), где он установлен, я могу правильно пройти аутентификацию с использованием учетной записи abc.onmicrosoft.com, но на последнем шаге функции это не удается.

Полезно, сообщение об ошибке UnknownErrorInner и проверки с помощью App Insights, я вижу сообщения журнала:
