What are PST Files?

In computing, the Personal Storage Table (PST) emerges as an exclusive file format designed by Microsoft. Its purpose is to store duplicates of emails, messages, calendar events, notes, and various other data for its suite of software applications, such as Microsoft Outlook.

The PST file serves as a widely used email storage format in Microsoft's suite. For example, Outlook preserves its data in PST file format. These Outlook PST files are stored in an Outlook file folder located within the documents folder on your computer.

However, if the PST files get corrupted for any reason, an Outlook user may lose all data. Therefore, knowing how to manage and protect PST files is essential to prevent data loss or attacks. Many users wonder how to backup PST files to OneDrive, that's why we are here.
