Modifing the Exchange owa error.aspx

Hi,

I would like to modify the "auth/error.aspx" for the exchange owa 2010 to do something special for one or two of the errors that can be returned to the aspx.

Below is the error.aspx.

I do not know enough about what would need to be changed in the code to do two things.

1.  Report the error exact error number to the user page so I can then set a redirect if that error occurs
2. Then set the redirect if that error occurs in the error.aspx

Could I ask for help on how to code this.

I attach the content of the aspx file.

Thanks

<html dir="<%=(SessionContext != null && SessionContext.IsRtl) ? "rtl" : "ltr"%>">

<% 	// Any urls to resources in this file, must be absolute urls.  The error page can load as a response to any request
	// made by the client, since it does by an internal redirect on the server and not as a 302 issued to the client.  
	// Therefore, there is no way of knowing where a relative url will take you.  For example, this page can load as a 
	// result of this request "http://servername/owa/auth/logon.aspx" or this request 
	// "http://servername/owa/ev.owa?oeh=1&ae=dostuff"

It's a bit tricky, because the error message is produced by compiled code that you can't see.  As you can probably guess, it is produced by the function RenderError(), but it isn't likely that you can get to see the actual error code for yourself.  One thing you might try is to use JavaScript to inspect the text once the page has been sent to the user.  To see if this is likely to work, try adding this just before the </body> tag at the bottom:

<script language="JavaScript">
alert(document.all.errMsg.innerText);
</script>

Hopefully, it will show a popup box with the same error text in it.

Thank you so much for you reply. That did pop up a box with the error
 Error box picture
So could I now jast say if the error contains the words "A mailbox couldn't be found for PROD\ whatever is next" do a refirect to :https://something?

How would I do that with a javaScript?

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Okay, that's good.  I would try replacing the script with:

<script language="JavaScript">
if(document.all.errMsg.innerText.indexOf("A mailbox coudn't be found") != -1)
  window.location = "http://servername/docname.htm";
</script>

use your own URL, of course.

HI. It did not do anything.  Do I need a * or something to get the part of the error?  Also do I need to use an absolute url or can i use https://servernams/dir/

<script language="JavaScript">
if(document.all.errMsg.innerText.indexOf("A mailbox couldn\'t be found") != -1)
 window.location = "https://owa.ugllimited.com/owa";
</script>

It needed an escape for the '.

Working now.  Thank you so much :)
