You are a desktop support technician for your company. All client computers run Windows XP Professional and run Microsoft Outlook Express as the default e-mail client.

You deliver the user name and password required for POP3 access to each user. You instruct each user
to configure Outlook Express with his or her user name and password.

One user reports that he must provide his credentials each time he starts Outlook Express. You discover that all other users are immediately allowed into Outlook Express without providing credentials.

A.
A signature is not created.

B.
An S/MIME certificate is not present.

C.
Outlook Express is not configured to remember passwords.

D.
Outlook Express needs to be directed to the Inbox folder at startup.
