I get this with EWS when I try to get emails from my adresse.
This my code and it was working fine
from exchangelib import Account, Credentials, Configuration, Message, DELEGATE, Mailbox, FileAttachment, HTMLBody, FolderCollection
from exchangelib.protocol import BaseProtocol, NoVerifyHTTPAdapter
from exchangelib.folders import Folder
import warnings
warnings.filterwarnings("ignore")
BaseProtocol.HTTP_ADAPTER_CLS = NoVerifyHTTPAdapter
credentials = Credentials(username='**domain\\XXXXXXXXXX**', password='**XXXXXXXXXXX**')
config = Configuration(server='**XXXXXXXXXXX**', credentials=credentials)
account = Account(primary_smtp_address='**[email protected]**', config=config, autodiscover=False, access_type=DELEGATE)
for email in account.inbox.all().order_by('-datetime_received')[:8]:
print(str(email.subject))
