In the past, most people used POP e-mail settings on their desktop e-mail clients such as Microsoft Outlook, Outlook Express, and Windows Mail.
Today, many people still use POP. However, IMAP has significant benefits if you use more than one computer to check your e-mail.
If you want to keep all your e-mails synchronized across multiple computers, then learn how to use IMAP settings because it could make your life much simpler. When you use IMAP, when you delete an e-mail on one computer, it deletes that e-mail on all your computers. So, you can run Outlook on all your computers and keep your e-mails synchronized all the time. Brilliant!
