exchangelib KeyError: 'contacts' or KeyError: 'inbox' or

Question

I want to search in contact list of some account and get that contacts details back, but none of folders that told here not work because of KeyError exception . Somehow i can't access to any of exchange account folders.

Is it permission or ... ?

Code :

from exchangelib import Credentials, Account, Configuration
from exchangelib.protocol import NoVerifyHTTPAdapter, BaseProtocol

BaseProtocol.HTTP_ADAPTER_CLS = NoVerifyHTTPAdapter

credentials = Credentials("YYY@XXX.com", 'PASSWORD')


account = Account(
    primary_smtp_address="Account@XXX.com",
    autodiscover=True, 
    credentials=credentials
)

print(account)  # work properly with printing my account
print(account.contacts)  # not work with KeyError Exception

Error :

Build version :

This method is work :

account.root.walk() # output : <exchangelib.folders.FolderCollection object at 0x03ADCA90>

But when i append filter to it above error occurred.

KeyError: 'folders'

only root folder is works fine and there is nothing in it !

print(account.root.all())  # QuerySet(q=Q(), folders=[Root (root)])

Answer 2

For the record, this turned out to be a misbehaving archive inbox folder. Workaround provided in https://github.com/ecederstrand/exchangelib/issues/431#issuecomment-409832287 by telling exchangelib to ignore this folder:

from exchangelib.folders import ArchiveInbox
from exchangelib.version import EXCHANGE_2016

# Set to something newer than your current version
ArchiveInbox.supported_from = EXCHANGE_2016
