The POP3 protocol allows E-mail clients to download messages from the server, but actions on the client side (such as moving messages, marking read, etc.) do not feed back to the server. For example, two emails in the mailbox were received by the client and moved to other folders. These emails on the mailbox server were not moved at the same time.

IMAP provides a two-way communication between webmail and E-mail clients. The operation of the client will be fed back to the server, and the operation of the mail will be acted upon by the mail on the server.

This means that when you log in to a mailbox using a web browser, the actions you perform on the E-mail client and mobile device (for example, moving the message to the "share" folder) are automatically reflected in the mailbox immediately (for example, the email already has a "share" TAB the next time you log in).
