Exchange 2010 Out of Office - Server Unavailable

We recently "upgraded" from 2003 with Exchange 2007 (Non SBS) to SBS 2011.

Since the upgrade users cannot use the Out of Office function, getting an error that the server is unavailable. They can access it via OWA.

Server is patched up to date.

We have checked the obvious things like the autodiscover paths.

Hi, pinging "autodiscover" from a workstation results in the new exchange servers ip being returned.

What outlook clients do you have?

What happens if you put

https://autodiscover.yourcompany.com/autodiscover/autodiscover.xml

into your web browser?

Well it's failing, but I'd expect it to, since it won't be able to resolve the autodiscover from externally as there is (and never has been) an autodiscover dns A record for external resolution.

You don't need an internal autodiscover record unless you have Mac clients or clients on your network that are not members of the domain but need to access Exchange.

Primary reason for this is SSL certificates issues, or incorrect configuration on the client access role.
Therefore the first thing to check is the Client Access Configuration.

get-clientaccessserver | select Identity, AutodiscoverServiceInternalURI

Ensure that the value for AutodiscoverServiceInternalURI is valid, resolves correctly and is on your SSL certificate.
Do you have a commercial SSL certificate?

If you want to access Exchange remotely, using Outlook Anywhere then you will need an external DNS record for Autodiscover.

Was the server configured using the wizards in SBS?

Hi There!

The get-clientaccesserver, returned two servers, both with the same url, and the old server is first, though I am not sure if that means it's primary or the list is just returning alphabetically.

The old server is still on the network, though it shouldn't be serving any purpose. We just haven't removed it yet. Should I remove it from the InternalURI?

Where does the URL resolve to? It should be resolving to the new server. That will mean that even if the old server publishes the URL to the domain, the traffic will be pointing to the new server.

Well EX1 is pointing to exchange.domain.com and EX2 is pointing to exchange.domain.com as well. So effectively they are pointing at the right place.

have you checked all of the other URLs on the Exchange 2007 server to see if they are now configured for the new server? It could be that something is being published wrong by autodiscover.

The problem was fixed with the latest service pack rollup for Exchange.
