We have an exchange 2010 deployment where I am unable to browse the OAB with https://ServerName/OAB everytime I do, I get 403 error saying "You do not have permission to view this directory or page using the credentials that you supplied" http redirection IS turned on for owa,I did make sure to only redirect the default website to OWA directory, I also added permissions for authenticated users to access web.config located at C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB, and I am still getting the same error :-( any ideas?

Hi Shah,
Thanks for your reply.
I'd say, the https://servername/oab/<GUID>/oab.xml should be available. So, please try the oab.xml to see if the permission is setup correctly. You may find the GUID number in the CAS server via folder C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB.
For the default virtual directory permission/authentication settings, see http://blogs.technet.com/b/exchange/archive/2010/09/23/3411146.aspx.
Regarding the Lync scheduler, there might be misconfigure or misunderstanding. Could you reproduce this issue? If so, please describe the steps in detail so that I can try in my local lab.
Best regards,
Fiona Liao

If you have HTTP redirection turned on for the Default Web Site, make sure you have it turned off for all subdirectories.

It is turned off for all subdirectories

It is by design that we are not able to open the OAB file via IE through https://servername/oab.
Can you tell us why you want to open it? Is there any problem for clients to download OAB? and what version client is it?

You're right, I shouldn't be able to open it via the browser but I shouldn't be getting 403 with credentials failing. I recently deployed Lync Server 2010 in our organization and everything is working except the lync scheduler cannot resolve the address book URL (for address lookup/scheduling), when I tried to access it directly it prompted me for credentials then denied access saying
403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.
which is NOT the expected result when browsing https:\servername\oab
I do have http redirection turned on for OWA but I made sure to not propagate those setting to sub-directories and I have checked and double checked them since Ed mentioned them as well.
Thanks,
Shah

I know this is an old issue but we are having issues downloading the offline address book. Do you have any resolutions?

Hello Fiona,
It is by design that we are not able to open the OAB file via IE through https://servername/oab
Can you provide a KB article so that we can refer and understand the behavior? I am also having same OAB isuse

Make sure that under /OAB, the file web.config has grants Authenticated Users Read and Read & Execute rights.
