title: Error using ColdFusion cfexchangeconnection to connect to Exchange server
body: <p>I am getting an error when trying to connect to an Exchange server using the cfexchangeconnection tag.  First some code:</p>
  
  <pre><code>&lt;cfexchangeconnection action="open" 
      server="****"   
      username="****" 
      password="****"
      connection="myEX" 
      protocol="https"
      port="443"&gt;
  </code></pre>
  
  <p>I know its the right server because it fails when not processing via https.  I have tried:</p>
  
  <ul>
  <li>Following all the instructions here <a href="http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec14f31-7fed.html" rel="nofollow noreferrer">http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec14f31-7fed.html</a></li>
  <li>Prefixing username with a domain name, adding @domain name, etc and no luck.</li>
  </ul>
  
  <p>The error I get is:</p>
  
  <pre><code>**Access to the Exchange server denied.**
  
  Ensure that the user name and password are correct.
  </code></pre>
  
  <p>Any ideas</p>
