.Hi User, please use IMAP.
** It offers two-way syncing between webmail and mail client actions. If you read a message in your email client, it will be marked read on the web!
** Save space by downloading only the message headers, or download whole messages to work offline.
** Your labels appear as folders, and vice versa, so it's easy to stay organized.
** Provides access to Drafts, Sent Mail and Spam folders.
** Great if you check your mail from multiple computers or mobile devices, you'll see the same messages and folders, no matter what email client you're using.
Here's a Link that you can check..

Are you still using Outlook Express? Why? Also, POP3 or IMAP account? – Karan – 2013-05-18T20:53:37.650
Using POP, and Outlook Express because it's an old machine and its user doesn't like changes. – user1049697 – 2013-05-18T21:12:30.307
1@user1049697 - POP3 doesn't support what you want. You would have to use IMAP. – Ramhound – 2013-05-18T23:38:17.720
