e mail that disapears

[The Third]

I have a pop mail account set up on my phone. My account is a road runner account from my outlook on my computer. I receive the e mails on my phone but after a short while they vanish. What, if anything can I do to keep these messages on my phone?

I my question not answerable or did I post it incorrectly?

They vanish from the phone when they vanish from the server. You download them to the computer and the next time the phone checks emails it finds them gone and then takes them off the phone.
