When configuring email clients you will be asked if you wish to use POP3 or IMAP to retrieve your mail. We are sometimes asked what the difference between these two methods.
In most cases, which method you use comes down to personal preference, however the main difference between each method is summarised below:
POP3 was originally designed as a way to download your email from the server; email on the server would then be removed.
The main advantage of IMAP is that it allows you to leave your email on the server all the time. This reduces the amount of email you need to download, and allows you to access all of your email from multiple clients (e.g. a desktop client and webmail) to suit.
