I have httpntlm node module installed into apigee and created an api-proxy. However the ntlmClient code which is making a GET request to EWS exchange service with right credentials always returns 401
But, the same ntlmClient which is run outside apigee as standalone node I get 200.
Node NTLM:
https://www.npmjs.com/package/httpntlm
We are using Apigee on-prem and Trieme version 0.8.9
