Exchange OAB expected response

I have a client that is running SBS 2008, they weren't using Exchange but the services were running and it seemed like some configuration had been done on it.   I setup the exchange server and got everything working except outlook would hang and eventually time out saying "the operation failed: an object could not be found"  I looked up the error code and it suggested they were having problems downloading OAB.  After much troubleshooting and trying various things, i have done the following setup:

rebuilt the OAB
changed url so it resolves to server correctly
set permissions to allow authenticated users on oab.xml
there was a web.config file created, changed permissions for read access to authenticated users

now, on the server,if i go to https://localhost/oab/<oabcode>/oab.xml  it loads the xml file fine

but if I browse to https://domainnamegoeshere.net/oab/<oabcode>/oab.xml  I am prompted with an authentication window, which does not accept my credentials, or any domain users, and after three tries returns a "401.1 - unauthorized" error

is this the expected response? os is my permissions for this web directory messed up?

thanks,

- Kalen

The OAB is located using Autodiscover.  Is ther a 3rd party SSL certificate installed (SAN / UCC - multi name) with the following names included:

remote.externaldomainname.com (or whatever you chose to use)
autodiscover.externaldomainname.com
servername.internaldomainname.local
servername
sites

Is there also an Autodiscover A record created externally in DNS that resolves to the IP address of your SBS server (public IP address not internal IP address)?

Thanks for the response

I would like to know what the expected response for browsing to that URL is?? and if it is to prompt for credentials, should a mailbox users credentials work????
















My SAN cert contains:
mail.externaldomainname.com
autodiscover.externaldomainname.com
sites

I have created all A records and added DNS entries on the server, to use external names, on internal network. i.e. browsing to autodiscover.externaldomainname.com internally resolves the exchange server correctly.

I used https://www.testexchangeconnectivity.com to verify and all tests pass.

this problem is only on the internal network

for anyone needing to know the expected response is to be prompted for credentials.  

In my case i could not get any credentials to work when browsing on the server.  But once i was at a workstation, browsing to the oab url prompted for credentials, autofilled the username, and i used the password for that user and it loaded the oab.xml.
