Detailed explanation-1: -POP works by contacting your email service and downloading all of your new messages from it. Once they are downloaded onto your PC or Mac, they are deleted from the email service. This means that after the email is downloaded, it can only be accessed using the same computer.
Detailed explanation-2: -By default, when you retrieve new messages from a POP3 email account, the messages are deleted from the POP3 mail server and then saved on the computer that you are using. Because the message is no longer on the POP3 mail server, you can’t see it when you connect from another computer.
Detailed explanation-3: -POP3 is an older protocol that was originally designed to be used on only one computer. Unlike modern protocols that use two-way synchronization, POP3 only supports one-way email synchronization, only allowing users to download emails from a server to a client.
Detailed explanation-4: -POP, or Post Office Protocol, is accessed from a remote server, but then all messages are downloaded directly and stored to your device and then deleted from the server. By deleting email copies on the server, storage usage stays lower.
Detailed explanation-5: -Yes, the IMAP sync deleted messages from server. It means, if you delete a message, it will get removed from the server. This article will guide you about IMAP synchronization.
