403 - Forbidden: Access is denied- For OWA

hi guys

I've set up Exchange but I can't get OWA to work externally. I can access it internally by going to https://servername/owa.

I have set up http redirect on all of the virtual directory folders, like 'Default Web Site', Autodiscover, EWS, Exchangeweb, OWA, Powershell, RPC etc. All of them have the checkbox 'Redirect requests to this destination' with the entries: https://mail.domainname.com/owa

The check box 'Only redirect requests to content in this directory' has also been checked.

On the firewall, I have done a redirect for anything hitting the external IP to the internal for ports 80 and 443.
I can't access it by the domain name yet as the 'A' record hasn't been set up.

But currently, when I type: https://external_IP/owa I get to the following error:

403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.

Any ideas guys?

Thanks
Yash

Yashy, this is not how redirects are setup.  Autodiscover, EWS, Powershell, RPC and OWA are *all* seperate services.

First, you need to rebuild your Exchange virtual directories:

Once completed verify that you can access OWA externally by the standard http address.

Then use the steps presented by Brian Desmond:

Note that he removes the redirection from the other Exchange related virtual directories.

Hey Saige,

Thank you for the response. I started the first step.  And i went on to the second step. However, when trying to login, then I get an error 'this webpage has a redirect loop'.

Any ideas what it could be?

You should be able to login without performing the second steps.  Check to ensure that the root website has redirection turned off.

All that has been done and I followed both guides. When I try to login with Chrome, I get the 'this webpage has a redirect loop' and if with IE then it literally does not login. It's trying to login but never does. It looks as though the redirect is now working correctly.
