OWA url redirection is wrong

**Mr.ken** · 21-07-2009

I don't what is happening with my Outlook Web Access. Its URL redirection is wrong for some reason that i don't know. What what i can guess is due to naming conventions and certificate issues, ISA is bridging external https to internal http.For external users access to OWA fails because the ISA publishing rule is no longer correct. How can i simplify the Outlook Web Access URL ?

With the help of Internet Information Services Manager, that is know as IIS, you can easily simplify OWA URL. To do so, just go through this simple steps:-

Open IIS Manager, and then navigate to Web Sites/Default Web Site. Right-click Default Web Site, and then click Properties.
Click the Home Directory tab, and then click the A redirection to a URL option.
In Redirect to, type /directory name. For example, to redirect https//server name requests to https//server name/exchange, in Redirect to, type /exchange.
If all the mailboxes that will be accessed by using Outlook Web Access are located on Exchange 2007 servers, you can replace /exchange with /owa. Doing this will redirect all requests to https//server name to https//servername/owa.
In the The client will be sent to: list, select A directory below URL entered.

Remember that the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group for the target server.

Redirection shouldn't be happening if both CAS roles are in the same AD site.In order to redirect user to HTTPS and simplify the OWA url, Create the following file in Notepad and save it to drive:\inetpub\wwwroot as SSLRedirect.htm, replacing <server name> with the name of your Client Access server:

<html>
<head>
<title>HTML Redirection to https:</title>
<META HTTP-EQUIV="Refresh"
CONTENT="1; URL=https://<servername>/exchange">
</head>
<body>
This page is attempting to redirect you to <a href="https:// <servername>/exchange/">https:// <servername>/exchange</a><br>
If you are not redirected within a few seconds, please click the link above to access Outlook Web Access.
</body></html>

Open IIS Manager, and then navigate to Web Sites/Default Web Site. Right-click Default Web Site, and then click Properties.Click the Home Directory tab, and then select A redirection to a URL.In Redirect to, enter /Exchange.Select The client will be sent to: A directory below the URL entered above.Click the Custom Errors tab, and then find HTTP Error 403;4 in the table. Click 403;4 to select it, and then click Edit.Click Browse to locate the file that you created at the start of this procedure.Click OK to save your changes.Open a Command Prompt window, and then type iisreset /noforce to restart IIS.

first check and make sure the external OWA URL is blank on the second Exchange server. Server Configuration > Client Access > Outlook Web Access > General Tab. General tab is used to view the properties of the Microsoft Office Outlook Web Access default Web site and to specify an external URL. Only the External URL can be modified.

Server (Read-only.) Server displays the name of the server that hosts the Outlook Web Access virtual directory.

Web site (Read-only.) Web site displays the name of the Web site.

Version (Read-only.) Version displays the version of Microsoft Exchange that the virtual directory supports.

Modified (Read-only.) Modified displays the last date and time that the virtual directory was modified.

Internal URL Use this text box to specify the URL that is used to access this Web site from an internal network. An internal URL is configured automatically during Exchange 2007 Setup. The default internal URL setting for an Internet-facing or non-Internet-facing Client Access server is https://<Computer Name>/owa.
