Hello all,

I want to set up an OWA web address like: to be able to access my email through OWA.

OWA and all facets are working, and I am able to access OWA through: http://PublicIP/exchange

how do I set up IIS on Server 2003 so that I can access my webmail through

I have spoken to the ISP and they will be setting up an appropriate 'A' record as soon as I am ready on my end.

Please help.

    If your ISP is setting up an A-record then in my eyes this should do it for you. Of course you have to type to access OWA. Or is "/exchange" what you wanted to avoid?

    Btw. make sure you setup SSL on your web server to encrypt your OWA traffic!

    Hi The Kirschi

    Yes sorry, it is the "/exchange" that I am wanting to avoid.
    I understand that I need to set up an alias/virtual hosting, but have no clue at the moment on how to do this.

    Please also answer how I would use SSL to encrypt my OWA traffic. Does this involve certificates ?

    Sorry, I m kinda new to the IIS thing...

    thanks in advance

    well actually I don't think that this is possible easily. It could be done if you have a http redirect somewhere in the internet that forwards your requests from to and then goes into your LAN. A redirect on your internal IIS won't work because of name resolution issues.

    For configuration of SSL see the following links:

    Alternativly you can use a certificate from a third party vendor such as Verisign or Globalsign.

    Hope this helps,

    First, get the redirection going:

    1. Create a new web site in IIS called Webmail, with a "Host header" of  and a path of C:\Inetpub\Webmail

    2. Create a file  C:\Inetpub\Webmail\Default.htm  and place the following in it:

    <meta http-equiv="refresh" content="1; URL=http://PublicIP/exchange">
    <p align="center">Hold on a second...</p>
    <p align="center">
    <a href= "http://PublicIP/exchange">
    <p align="center">If you are not redirected automatically within a few
     seconds then please click on the link above.</p>
    <script language="JavaScript"><!--
    function Redirect()
     location.href = 'http://PublicIP/exchange';
    // --></script>

    Now, to get OWA working with Forms Based Authentication (requires SSL / HTTPS, which requires a certificate), have a look at:
