title: Graph API - get events returning 500 internal server error
body: <p>Trying to use the Graph API (through <a href="https://developer.microsoft.com/en-us/graph/graph-explorer/" rel="nofollow noreferrer">https://developer.microsoft.com/en-us/graph/graph-explorer/</a>) to return events from a shared calendar using the following endpoint:</p>
  
  <pre><code>https://graph.microsoft.com/v1.0/users/&lt;user&gt;/calendar/events
  </code></pre>
  
  <p>When <code>&lt;user&gt;</code> is replaced with my email, the events are returned as expected, however if it is replaced with a colleague (who has shared the calendar with me), I get the following <code>500</code> response:</p>
  
  <pre><code>{
      "error": {
          "code": "ErrorInternalServerTransientError",
          "message": "An internal server error occurred. Try again later.",
          "innerError": {
              "request-id": "b26e5b81-56f0-40b6-bb7b-89c1508c4c77",
              "date": "2017-05-25T13:11:16"
          }
      }
  }
  </code></pre>
  
  <p>Fairly new to the Graph API, so any guidance would be appreciated.</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Just tried to replicate this using a local node.js server, I followed the following example (every step worked fine): <a href="https://docs.microsoft.com/en-us/outlook/rest/node-tutorial" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/outlook/rest/node-tutorial</a></p>
  
  <p>However, when I create a new function to fetch the calendar of my colleague, I get the similar response from before:</p>
  
  <pre><code>ERROR:{
     "statusCode":500,
     "code":"InternalServerError",
     "message":"Error while processing response.",
     "requestId":"65fa8d30-3bbf-498c-869f-f4bb89bec8d5",
     "date":"2017-05-25T19:13:07.000Z",
     "body":{
        "code":"InternalServerError",
        "message":"Error while processing response.",
        "innerError":{
           "request-id":"65fa8d30-3bbf-498c-869f-f4bb89bec8d5",
           "date":"2017-05-25T19:13:07"
        }
     }
  }
  </code></pre>
