Exchangelib连接到Office 365共享邮箱失败

Question

我需要编写一个Python脚本，该脚本在Office 365上托管的共享邮箱中检查传入的电子邮件。

我使用了Python fiffangelib 4.7.3：

code

#!/usr/bin/env python3

import logging
from exchangelib import Credentials, Account, Configuration, DELEGATE


def list_mails():
    credentials = Credentials('[email protected]', 'SecretPassword')
    config = Configuration(server='outlook.office365.com', credentials=credentials)
    account = Account(primary_smtp_address='[email protected]', config=config, autodiscover=False, access_type=DELEGATE)

    for item in account.inbox.all().order_by('-datetime_received')[:100]:
        print(item.subject, item.sender, item.datetime_received)


def main():
   list_mails()

if __name__ == "__main__":
    logging.basicConfig(level=logging.DEBUG)
    main()

问题

不管不同的尝试，以下错误正在显示：

尝试解决方案（没有运气）

• [email＆nbsp; preected] 凭据有效，我可以在Web界面中登录自己（没有MFA或其他强制性），
• 我已经尝试了自动发现： account =帐户（'
• 按建议连接时禁用TLS验证，
• 添加了on.company.com上的“ on” subdomain in.company.com上的电子邮件地址。
• 测试了自动发现的整体设置
