Exchange 2010 and removing AD Sites

A customer removed AD Sites because of restructuring AD Sites to a central AD Site.

Exchange Application Log reported:
Unhandled Exception "User setting 'PreferredSite' is not available"
Source: MSExchange Autodiscover
Level: Error

Exchange 2010 has an Active Directory dependency and both Exchange Client Access Array en Client Access Server make explictit use of AD Sites.

Solution is to reconfigure Exchange for the new AD Site:
Set-ClientAccessArray Name-CAS-Array –Site Name-AD-Site
Set-ClientAccessServer Name-CAS-Server – AutoDiscoverSiteScope Name-AD-Site
