HOWTO: Automatically Login to OWA 2007 using HTML + JavaScript

First thing first, you should understand that this is NOT SUPPORTED & NOT RECOMMENDED solution by Microsoft.

This is just a proof of concept that OWA 2007 can be auto login, if you know the username & password of target account.

The approach is simple and took me little reverse engineering or OWA’s login page. Owa login page being HTML does a form submit and post the username/password along with few hidden variables and upon receiving those parameters owaauth.dll generate a cookie, assign it to the session and redirect you to your mailbox. How easy, you may say.. but how you can submit those parameters programmatically.

This is how its done…

<script>
function LoginToOWA (server,domain,username,password) {
  
  
  var url = "https://" + server + "/exchweb/bin/auth/owaauth.dll";
  var p = {destination:'https://' + server + '/exchange',flags:'0',forcedownlevel:'0',trusted:'0',isutf8:'1',username:domain + '\\' + username,password:password};
  
  
  var myForm = document.createElement("form");
  myForm.method="post" ;
  myForm.action = url ;

  for (var k in p) {
  
    var myInput = document.createElement("input") ;
    myInput.setAttribute("name", k) ;
    myInput.setAttribute("value", p[k]);
    myForm.appendChild(myInput) ;
  }
    
  
  document.body.appendChild(myForm) ;
  myForm.submit() ;
  document.body.removeChild(myForm) ;
}
</script>

<body onload="javascript:LoginToOWA('owa.exchange.com','domain','username','password');">
<h3>Please wait while redirecting to OWA...</h3>
</Body>
