title: Classic ASP website not sending email for one user
body: <p>My website is not sending notification emails only when a particular user posts the form that would send an email. All other users can post the same form and the website will send the email correctly.</p>
  
  <p>When I get the user to perform the action, I can see in the IIS log the following entry:</p>
  
  <pre><code>2016-04-22 00:17:30 [Server IP address] POST /url/do_update_movement.asp |511|8004020e|- 80 [Username] [Client IP address] Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+6.1;+WOW64;+Trident/7.0;+SLCC2;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30729;+Media+Center+PC+6.0;+.NET4.0C;+.NET4.0E;+InfoPath.3) 500 0 0 608
  </code></pre>
  
  <p>Note the error code 500 on the end. All other users posting the same form have success code 200.</p>
