QuestionYou are a messaging professional. Your company uses a Microsoft

Exchange Server 2003 messaging system. Your company deploys Microsoft Exchange Server 2007

Mailbox servers and Exchange Server 2007 Hub Transport servers within the existing messaging system.

One Client Access Server is also deployed. Client computers run Microsoft Office Outlook 2003.

You move 50 user mailboxes to a new Exchange Server 2007 Mailbox server. These 50 users report that

access to public folder information and free/busy information for other users is very slow.

You need to ensure that all users continue to have access to public folders and can see the free/busy times

for other users after their mailboxes are moved to an Exchange Server 2007 Mailbox server.

What should you do to ensure that all users continue to have access to public folders and can see the free/busy times

for other users?

A.
Add the Unified Messaging server role to an existing Exchange Server 2007 computer. Configure an
autodiscover record for the Unified Messaging server in the Domain Name System (DNS) zone.

B.
Add a new Edge Transport server. Subscribe the Hub Transport servers to the Edge Transport server.

C.
Create a replica of the Exchange Server 2003 public folders on the Exchange Server 2007 Mailbox servers.

D.
Add another Client Access Server. Implement a Network Load Balancing cluster.Reset Instructions
