问题描述
我使用库exchangelib随机遇到身份验证错误：
from exchangelib import DELEGATE,Account,Credentials
creds = Credentials(
username=username,password=pw)
account = Account(
primary_smtp_address=mailbox_mail,credentials=creds,autodiscover=True,access_type=DELEGATE
)
account变量的定义会导致以下错误，但是在相关文档中找不到原因或有用的地方：

这很奇怪，因为此错误似乎是随机发生的。 发生此错误时，我只需重新运行代码即可立即开始工作。
我使用exchangelib == 3.2.0和Python 3.7。
