Removing Exchange 2010 server after migration to 2013

Hi All,
I've migrated all our useres and services to a new Exchange 2013 system and am ready to uninstall Exchange 2010.
However, to see how the system would work without the 2010 box, I shut it down. All worked fine mostly, but autodiscover took 45seconds rather than being instant. This has an impact on Outlook users with mandatory profiles as they look up their account details each time they logon and use Outlook the first time.
I'm guessing this slowness is because autodiscover is looking for the 2010 box through SCP but failing and it will be fine after 2010 is uninstalled and it's information is removed from AD?

You need to check where Autodiscover is looking. If you haven't changed the URL then you probably have an Autodiscover war going on. That would mean that another time when you did the same test, there would be no problems.

get-clientaccesserver | select identity, AutodiscoverServiceInternalURI

Make the two URLs the same, which will mean both servers will publish the same host to the domain. That will avoid the problem.

Obviously when you remove Exchange 2010, it will no longer publish the Autodiscover value to the domain, and the Exchange 2013 server will.
