You have an Exchange Server 2010 organization.

All users on the network run Microsoft Office Outlook 2010 to access their mailboxes. Outlook 2010 is configured for Outlook Anywhere by using Autodiscover.

You create a Client Access server array named outlook.contoso.com. You verify that all computers can resolve outlook.contoso.com.
