Please configure the mailbox in your email client. Please use the IMAP protocol instead of POP3. The IMAP protocol is more modern than the POP3 protocol. The latter only allows retrieving and deleting emails from the mail server. However, the IMAP protocol allows synchronized management of folders and emails both on the mail server and on the client. Since the client and mail server are automatically synchronized, it is thus possible to access the same mailbox from multiple devices. Moreover, the IMAP protocol also allows uploading emails from the computer to the server. You can therefore copy emails from your old mailbox that are already saved on your computer into the new mailbox.
Guides for configuring the new account with different email clients are available:
