After setting the security feature 'extended protection for exchange' i had the same problem (SOAP 401). Now i have to use CURLAUTH_BASIC instead of CURLAUTH_NTLM.

Current status for anyone arriving from Google:

Username and password authentication has been removed as per October 2022 for exchange servers on 365.

So you will have to change authentication to oauth or use a different library.

There is a comment about it on this issue: https://github.com/jamesiarmes/php-ews/issues/212#issuecomment-1275400001

I got a 401 response for every SOAP Request and also struggled to find out why.

Running Ubuntu, curl version: 7.35.0.

As pointed out here "CURLAUTH_BASIC" should be removed in NTLMSoapClient.php from line:

curl_setopt($this->ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC | CURLAUTH_NTLM);

so that it only says

curl_setopt($this->ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM);

This works for me for jamesiarmes/php-ews project.

In garethp/php-ews though, (which seems to offer quite a lot of convenience methods for querying the exchange server), setting the curl authentication method moved to src/API/ExchangeWebServicesAuth.php.

EDIT: See curl docs for more info on authentication methods.
