Converting an .OST file into a .PST file requires a third party application, Outlook cannot do this by itself.  What you can do is export it to a .PST.  I assume you're doing this for backup purposes, an email account that uses an .OST file cannot use a .PST file instead.  If not, what are you attempting to achieve?
