Detailed explanation-1: -That being said, there are definite disadvantages to using POP. Problems can quickly arise if you’ve set this up on more than one device, as there’s no synchronization between the server and clients. So if you read, process, delete, etc. email on your computer, you will not see those changes on your tablet or phone.
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.
Detailed explanation-3: -POP3 is insecure because it processes emails locally and downloads both attachments automatically. While you can add TLS/SSL to POP3 servers, the protocol does not support most modern features that make email transfer flexible and feasible for organizations.
