You may not have "Basic Authentication" enabled on ews virtual directory, it is not enabled by default. you have to enable this after configuring server.

following command help enable basic authentication.

Set-WebServicesVirtualDirectory -Identity Contoso\EWS* -BasicAuthentication $true

make sure you know what you are doing before running above script, exposing basic auth without SSL may expose your credential to wild.

Hi I have the exact same problem. I belive it is caused by not trusting server cert. I also tried C++ api and I had problem with certificate but there was an option to disable certificate check and it works. I don't know how to disable certification check in this api.

I have one more question. How can I make the script work when I open index.html in browser. I tried browserify but no luck.

from ews-javascript-api.

browser has XHR cross site limitation, Exchange does not support HTTP OPTION verb, no point using browser. you can use it in nw.js or in ElectronJS projects as npm module

@guderkar see #190 fro browser specific detail, you need to disable CORS if you want to test in browser. works in Electron's renderer process
