Performing redirects to the /OWA directory is something most Exchange Admins have come across. Nicolas Blank covers it in his blog, Redirecting from / to /owa, perfectly.
Simple, create a text file called “default.asp” and place it in the virtual directory that is handled by webmail.domain.com and place the following code inside it. Just Remember to replace domain.com with your own domain name.
<html>
<head><meta http-equiv="REFRESH" content="0;url=https://webmail.domain.com/owa">
/head>
</html>
There can be problems using Meta REFRESH (see here), so with Safari and Firefox Premium OWA support in Exchange 2010 we should use JavaScript for the best experience.
We may also want to setup a HTTP to HTTPS redirect for those users who do not type “https://…”.
<html>
<head runat="server">
<title>Outlook Web Access</title>
<script language="javascript" type="text/javascript">
function redirect()
{
var URL;
var Protocol;
var Path;
// this will be whatever is in the browser. If you need to change this then comment out relevant line below
// Protocol = window.location.protocol + "//"
// Protocol = "http://"
Protocol = "https://"
Path = window.location.hostname + window.location.pathname + "owa"
window.location.href = Protocol + Path
}</script>
</head>
<body onload="redirect()">
</body>
</html>
For best results set the root of the web site not to require SSL and all virtual directories (OWA, EWS, etc) to require SSL.
