Overview – OST and PST File Formats

For new users, there is little distinction between OST and PST files. Essentially, both Outlook data file types have the same file structure. They both save the same type of mailbox data. However, there is a significant difference between OST and PST files. Novice users can be unaware of it. Outlook data files, including OST and PST, contain email, contacts, calendar, tasks, notes, and other mailbox data, including attachments. When Outlook is used as an independent program, it produces PST (personal storage tables).

On the opposite hand, if the Outlook program is linked to an Exchange Server by Microsoft and the Cached Exchange Mode is enabled, a copy of your mailboxes is saved to the local machine’s system internal file known as OST (Offline Storage Table).

Unlike PST, an OST file does not require an internet connection to access emails and other mailbox databases. In offline mode, you can make appointments, add new contacts, read and compose emails, and so on. As soon as connectivity to the internet is restored, any modifications you performed previously will be synchronized with the Exchange Server. Still, if there is something wrong with the Exchange server from Microsoft Server, the OST file will be unaffected.

Why Do Users Require to Convert OST files to PST format?

There are numerous instances in which we need to export an offline OST file to PST file format, such as when the OST file becomes unreachable due to a sudden power outage, the exchange server crashes, the OST file becomes orphaned due to a change in Outlook profile, or the user needs to retrieve another OST file in the same Outlook, among others.
By converting Outlook OST to PST file format, data can be restored even after user mailboxes on the Exchange server have been accidentally deleted.
