You are a desktop support technician for your company. All client computers run Windows XP Professional and Microsoft Office XP.

The company uses a Microsoft Exchange Server 2003 computer for all messaging. The Exchange server is configured to accept POP3, IMAP4, and SMTP connections from remote users. The server is configured to allow SMTP relaying from authenticated users only.

A user reports that he has just received a new portable computer. The user states that he can receive e-mail by using POP3, but he cannot send e-mail. You confirm that the user can make SMTP connections to the Exchange server. You also confirm that Outlook is configured to have the proper SMTP server address.

You need to ensure that the user can use Outlook to send e-mail from his new computer.

What should you instruct the user to do?

A.
Configure Outlook to act as an IMAP4 client.

B.
Configure Outlook to work only with message headers.

C.
Configure Outlook to use encrypted SMTP connections.

D.
Configure Outlook to use his POP3 credentials to authenticate to the SMTP server.
