我试图使用python中的exchangeelib库连接到我的官方邮件服务器，但遇到错误
HTTP连接池（主机=“mail.domainnam.in，"矶钓=443）：读取超时.（读取超时=120）

def send_mail(content):
    # Load environment variables from the .env file
    load_dotenv()

    # Access environment variables
    outlook_user = os.getenv('OUTLOOK_USER')
    outlook_password = os.getenv('OUTLOOK_PASS')
    outlook_server = os.getenv('OUTLOOK_SERVER')
    outlook_email = os.getenv('OUTLOOK_EMAIL')

    credentials = Credentials(
        username=outlook_user,
        password=outlook_password
        )

    config = Configuration(
        server=outlook_server,
        credentials=credentials
        )

    account = Account(
        primary_smtp_address=outlook_email,
        config=config,
        autodiscover=False,
        access_type=DELEGATE
        )

    msg = Message(
        account=account,
        subject="Test Mail",
        body=content,
        to_recipients=["email_address_1"],
        cc_recipients=["email_address_2"]
        )
    msg.send_and_save()
