Google Apps - This account cannot be accessed because we could not parse the login request

Question

I want to do SSO through SAMLResponse, which is generated after receiving the authrequest from Google. But with outlook, I have found that error:

Google Apps - This account cannot be accessed because we could not parse the login request.

Email address and cert is hide due to security.

SAML response is given below:
