title: Graph Explorer ErrorInvalidIdMalformed
body: <p>I am using</p>
  
  <pre><code>https://developer.microsoft.com/graph/graph-explorer/
  </code></pre>
  
  <p>to test out some things.  When I use</p>
  
  <pre><code>https://graph.microsoft.com/v1.0/me/mailFolders
  https://graph.microsoft.com/v1.0/me/mailFolders/Inbox/messages
  </code></pre>
  
  <p>I get what I expect,  a list of my folders and messages in my Inbox.  When change me to my email address I get the same information.  Now when I try using a different mailbox I have access to and try to get the messages in "Interesting Messages" I get the ErrorInvalidIdMalformed.  I assume the issue is the space in the path</p>
  
  <pre><code>https://graph.microsoft.com/v1.0/users/otheremail@company.com/mailFolders/Interesting Messages/messages
  {
  "error": {
      "code": "ErrorInvalidIdMalformed",
      "message": "Id is malformed.",
      "innerError": {
          "request-id": "f47d4c3b-5681-4b83-b8f4-c2b9be591ff6",
          "date": "2019-02-07T22:39:31"
      }
  }
  </code></pre>
  
  <p>I've tried using %20 instead of the space and I still get the error.  Is there a way of having spaces in the URL or do I need to get the mailbox renamed?</p>
  
  <p>TIA,
  Joe</p>
