Detailed explanation-1: -The post office protocol (POP) is the most commonly used message request protocol in the Internet world for transferring messages from an e-mail server to an e-mail client. With POP3, the e-mail client requests new messages from the e-mail server, and the server “pops” all new messages out to the client.
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: -Disadvantages of POP3 Emails cannot be accessed from other machines (unless configured to do so). Exporting the local mail folder to another email client or physical machine can be difficult. Email folders can become corrupted, potentially losing the entire mailbox at once.
Detailed explanation-4: -POP3 (Post Office Protocol 3) is the email retrieval protocol used to receive emails from the server. POP3 downloads the original emails from the email server on a single device/computer. Then it deletes the emails from the server’s inbox. It lacks synchronization; thus, several devices cannot access the same email.
