There are many reasons why a user may need to convert OST files to PST format. Both OST and PST are Outlook data files which store the mailbox content. Although both these files store the same type of data, they’re different from each other. OST is an offline storage table, whereas PST is a personal storage table.

OST  (Offline Storage Table)

If you’re using an Exchange account, you can enable the “Exchange Cache Mode” in order to save a copy of your mailbox content on the local system. This local copy is called the OST file. OST, as the name suggests, allows users to work in offline mode when the Internet connection is unavailable. And when the connection is re-established, you can synchronize the changes you made while you were offline.

PST (Personal Storage Table)

If you’re using the Outlook client as a stand-alone application, it creates an Outlook data file on your system, called PST. It stores mailbox content like email messages, contacts, calendars, tasks, notes, journals, attachments, and much more. Unlike an OST file, you can’t use the PST file offline, i.e. without an Internet connection. In order to access and use the PST file, an Internet connection is mainly required.
