A Problem of Using Python to Link to Local Exhcnage Server EWS

[linseasea]

Exchange Server Type: Local

Operating system: macOS

Python version: 3.11

Library used: exchangelib 3.3.0

Exchange Server Version: Exchange 2016

The link information I have:

1. Exchange server local administrator account and password

2. The IP address of the exchange server

3. Email account for company domain name

Action taken:

1. I'm trying to open it https://mycommanymail.com/ews/exchange.asmx And successfully logged in.

My script:
from exchangelib import DELEGATE, Account, Credentials

credentials = Credentials(
username='172.19.32.12\admin', # Or me@example.com for O365
password='co00kewq#9'
)
a = Account(
primary_smtp_address='lucius@company.com',
credentials=credentials,
autodiscover=True,
access_type=DELEGATE
)

Print first 100 inbox messages in reverse order

for item in a.inbox.all().only('subject').order_by('-datetime_received')[:100]:
print(item.subject)

My error info:

If you already know the hostname og the Exchange server, then there's no need to use autodiscover.

New code：
from exchangelib import DELEGATE, Account, Credentials

credentials = Credentials(
username='172.19.32.12\admin', # Or me@example.com for O365
password='co00kewq#9'
)
a = Account(
primary_smtp_address='lucius@company.com',
credentials=credentials,
autodiscover=False,
access_type=DELEGATE
)

New error：

Please read the docs on creating a connection without autodiscover: https://ecederstrand.github.io/exchangelib/#optimizing-connections

Closing as I don't think this is an issue with exchangelib.
