IMAP (Internet Message Access Protocol) is the recommended method when you need to check email from several different devices, such as phones, laptops, and tablets. IMAP allows you to access your email wherever you are, from any device. When you read email messages that use IMAP, you don't actually download or store them on your computer; instead, you've read from an email service. As a result, you can check your email from any other device, anywhere in the world: cell phone, computer, computer friend.
IMAP only downloads the message when the message is clicked, and attachments are not downloaded automatically. Thus, you can view messages much faster than using POP.
