Yes with POP you will have PST and OST is only with Exchange. Please make sure it is exchange. If it is POP account no need to convert. It is already in PST format.  ..... so are you looking tool for converting? Here is the most powerful and reliable is the Recovery Toolbox for Outlook.  https://osttopst.recoverytoolbox.com/
