You have an Exchange Server 2007 organization.

All users on your network run Microsoft Office Outlook 2007 to access their mailboxes. Outlook 2007 is configured to connect using RPC over HTTP and Autodiscover.

You perform a Typical installation of Exchange Server 2010 on a new server, and then move mailboxes to the new server. Users now report that they cannot access their mailboxes.

You need to ensure that all users can access their mailboxes.

What should you do from the new server?

A.
Run the Switchover Server wizard.

B.
Enable and configure Outlook Anywhere.

C.
Create and configure a Client Access array.

D.
Rename the OWA virtual directory to Exchange.
