Most Outlook users would have heard the terms "OST" and "PST" at one time or another. Though both of these formats are used to save Outlook data, there is a difference between the two.
OST or "Offline Storage Table" stores all of the works that were done while Outlook was online, with a local "offline storage table" created for when it is offline, thus saving having to download the data all over again when going back online. An example of when an OST file is used is when Outlook is connected to a Microsoft Exchange Server, or any other email server via IMAP (Internet Message Access Protocol).
Another way Outlook data is stored is in a PST file. In this case, everything is stored (and remains accessible) in the Personal Storage File when offline.
