What is a .PST file?

A .PST file, which stands for Outlook Personal Information Store, is a type of data file used by Microsoft Outlook and Microsoft Exchange to store a user's personal information. This file format is specifically designed to hold a variety of important data such as email messages, email folders, contacts, calendar events, and other personal information. The .PST file allows users to store their email communications and related data in a single, local file, making it easier to manage and backup personal information.

To access or manage the contents of a .PST file, several programs are available: 1. **Microsoft Outlook 365** - This is the latest version of Microsoft Outlook, a part of the Microsoft Office suite, which can open and manage .PST files. It provides tools for reading emails, managing calendars, and organizing contacts stored in the .PST file.

2. **Microsoft Exchange Server** - This is a mail server and calendaring server developed by Microsoft. It can work with .PST files when setting up connected accounts that store data locally.

4. **Remo Repair Outlook (PST)** - This is a specialized tool designed to repair corrupt or damaged .PST files, helping users recover their important data.

5. **Encryptomatic PSTViewer Pro** - This program allows users to view, search, and manage emails within .PST files without the need for Microsoft Outlook. It can be particularly useful for those who need to access archived emails.

6. **OEmailRecovery.com Outlook Recovery Toolbox** - This tool focuses on recovering data from damaged or corrupt .PST files, ensuring that users do not lose valuable information.

7. **Regain Outlook PST Recovery** - Another recovery tool that helps in restoring and repairing .PST files, making it possible to regain access to lost or inaccessible data.
