exchangelib with OAUTH2 get error : exchangelib.errors.MalformedResponseError: Unknown failure in response.

[zx2015]

I got error message "exchangelib.errors.MalformedResponseError: Unknown failure in response."
Could you help?

My code:

credentials = OAuth2Credentials(
    client_id = client_id,
    client_secret = client_secret,
    tenant_id = tenant_id
)

config = Configuration(
    credentials = credentials,
    auth_type = OAUTH2,
    service_endpoint="https://outlook.office365.com/EWS/Exchange.asmx",
    version=Version(build=EXCHANGE_O365)
)

account = Account(primary_smtp_address=username,
                  credentials=credentials,
                  config=config,
                  autodiscover=False,
                  access_type=IMPERSONATION)
folder = account.inbox
for email in folder.all().order_by('-datetime_received')[:10]:
    print(email.subject, email.sender.name, email.datetime_received)

Error messages I got:

Your output contains this error message: "The token contains not enough scope to make this call". So it's an issue with your OAuth token.

Got it. Thanks

@zx2015 @ecederstrand What was the fix or root cause then? I have the same problem now, and I'm unaware if I am doing something wrong on the Python code side or the account settings deny the email reading?
