After it connects to the email server, it fetches whatever content you requested, like all new email or the contents of a specific message. This is cached locally, so you can work on your device.
Once you make changes to your email, such as deleting messages or sending a new email, the server processes and saves these changes, then disconnects. You aren't downloading local copies of all your messages; you're using the email client to manage the email stored on the server. The only information stored on your device unless you explicitly download something are cached copies for efficiency. POP was designed for a simpler time when you only needed to access your email from one device.
In those days, constant internet access also wasn't common, so POP made sense for dial-up connections where you got online, did what you needed, and then disconnected. It thus has the following pros:. POP has some advantages in specific situations, but it's largely outdated today. It's not designed for checking email from multiple devices, so you can experience problems even if you leave a copy of email on the server.
For instance, if you delete an email on one device, that deletion doesn't sync to the server, so other devices will still have that message. And since each device downloads every message from the server, it's easy to end up with a bunch of duplicates and not know what you've already dealt with.
Downloading every message from your POP account can use up a lot of space on your device, depending on how much mail you have. A lot of POP use today is to access mailboxes provided by your ISP, web hosting company, or similar, which tend to suffer from extremely limited storage.
