Connecting with EWS API service to outlook.com account with oAuth2 token

Question

I'm able to authenticate with live.com with my account on outlook.com at url

https://login.microsoftonline.com/common/v2.0

I receive an accessToken and id token.

My question is whether I can use this accessToken to retrieve exchange data about my emails through EWS API service using this token?ExchangeService.

   _exchangeService = new ExchangeService(ExchangeVersion.Exchange2007_SP1) { ConnectionGroupName = Guid.NewGuid().ToString() };
                    _exchangeService.Credentials = new WebCredentials("xxxxxxx", "xxxxxxxx", "outlook.com");
                 //  _credentials = new OAuthCredentials(user.PasswordToken);
                    // Set the URL.
                    _exchangeService.TraceEnabled = true;
                    _exchangeService.AutodiscoverUrl("xxxxx")

My question is whether I can retrieve email data from exchange service ASMX with the idToken/accessToken supplied from live.com for outlook.com accounts?
