An OST (Offline Storage Table) file is a data file used by Microsoft Outlook to store a synchronized copy of your mailbox data from an Exchange server, allowing offline access to emails, calendar events, and contacts. It enables users to work without an internet connection, with changes syncing back to the server once reconnected. OST files are particularly useful for data recovery when the Exchange server is unavailable. If you need to convert an OST file to a PST file for backup or migration, you can use either manual methods in Outlook or specialized third-party software tools.

A PST (Personal Storage Table) file refers to a file format that is exclusive to Microsoft and used for storing message copies, calendars, contacts, and other information within Microsoft Outlook as well as other Microsoft applications. Such source file exists as a local distribution in the user’s folder thus enabling such users to view their contents offline. PST files are also popular for the storage of Emails and are designed in such a way that they can be used in several installations of Outlook. They can, however, be damaged when the maximum size limit is reached or when used incorrectly, thus the need to make spare copies and carry out preventive maintenance regularly.
