You have an Exchange Server 2003 organization. All users connect to their mailboxes by using
Microsoft Office Outlook. You start to transition the organization to new Exchange Server 2010
servers. The new servers are on a secured subnet that is separated by a firewall. You will move half
of the mailboxes to the new servers. Client Access servers and Mailbox servers are on the secured
subnet. Client computers on the network can access the Client Access servers. You need to
recommend a solution that allows users to connect to Public Folders by using Outlook or Outlook
Web App (OWA).
