IPhone Email Difficulties - POP and IMAP? - 1

I currently have 3 email accounts set up on my iPhone. The primary one has recently somehow changed itself from a IMAP account to a POP account. I can no longer access older emails, like I had been able to with my IMAP account. The other two emails have stayed IMAP accounts. Is there any way for me to change it back. I'm thinking that this may have been caused by me beginning to use the Mail app on my MacBook? Not sure, but any guidance would be greatly appreciated.
