When you set up on your email addresses on your chosen software you have the option of choosing between POP3 and IMAP. They both allow you to access your email address but behave differently so you need to choose the best option for you.
POP3
If you use POP3 your emails are downloaded from the mail server onto your computer. Once downloaded the email is deleted from the server (unless you set your email software to leave all the emails on the server). If you use more than one computer or device (tablet or smart phone) to access your emails you could well find that emails you have already viewed only appear on the one computer – in other words if you download it to your desktop it then won’t be available to view on your phone.

IMAP
IMAP, on the other hand, stores emails on the mail server. What it does is sync your emails between the mail server and any computers/devices you use. It also syncs any emails you have sent with the server – so you can access your sent emails on your phone if when you’ve sent them from your computer. This makes it the better option if it’s important to you to be able to have access to all your emails on all your devices. However, because all your emails are stored on the server you have to be aware of how much storage space you have and monitor it to make sure you don’t fill up your mailbox. A full mailbox means that you won’t be able to receive any new emails, they will instead bounce back to the sender.

Beware
Just a word of warning. Many of the current email programs, for example Outlook, try to automatically choose your email settings for you and quite often default to IMAP. When setting up your emails please be aware of the settings and make sure you choose the options which best suit you and your mailbox storage allowance.
