What is the Difference Between PST and OST Files?

OST File Format: OST files are binary copies of Exchange Server mailbox folders. These files are generated automatically if the mailbox folder is accessed. The .ost files are synchronized with the server copy of the mailbox whenever the Exchange server is connected. An OST file is an offline copy of an Exchange mailbox. It allows users to work with their mailbox data even when they are not connected to the Exchange server.  When Outlook uses Cached Exchange Mode, it generates an OST file on the user’s computer. This file stores a synchronized copy of the user’s mailbox, enabling them to access emails.

PST File Format: A PST file stands for a personal storage table, and it is a file format used by Microsoft programs. It is used to store items such as contacts, calendar events, and email messages. Also, it helps users access server mailboxes and allows them to create local archives of email folders that exist on server-based email clients. Users can create PST files to archive old emails, free up space on the mail server, or create backups of their mailbox data. PST files are portable and can be moved or imported into many Outlook profiles. By default, PST files are stored on the user’s PC but they can be moved or copied to other locations, such as external hard drives or network storage. Users can manually back up PST files to create a snapshot of their mailbox at a specific time. This is useful for archiving, migrating data to a new system, or restoring data.
