What is a PST File?
A PST file (Personal Storage Table) is a proprietary file format used by Microsoft Outlook to store email messages, calendar events, contacts, tasks, and other data. PST files serve as local archives of your Outlook mailbox and can contain thousands of emails organized in folders. These files are essential for backing up Outlook data, migrating between computers, or archiving old emails.

Why Choose Our PST Viewer?
Our online PST viewer eliminates the need for Microsoft Outlook installation just to view archived emails. Whether you need to access old emails from a backup, review PST files on a Mac or Linux system, recover emails from a corrupted Outlook installation, or simply browse PST contents without importing them into Outlook, our tool provides instant access. The viewer works entirely in your browser, ensuring your sensitive email data remains private and secure.
Common Use Cases
This PST viewer is ideal for IT administrators managing email archives, legal professionals reviewing email evidence, businesses accessing historical communications, individuals migrating between email systems, and anyone who needs to open PST files without Outlook. The tool is particularly useful when working on non-Windows systems or when you need quick access to PST contents without the overhead of a full email client.
Technical Limitations
Please note that PST files use Microsoft's proprietary format which is highly complex. While our viewer handles basic email viewing and folder navigation, very large PST files (over 2GB) or files with advanced features may have limited support. For comprehensive PST management, data recovery, or migration tasks, we recommend using Microsoft Outlook or specialized PST recovery software. This viewer is designed for convenient, quick access to PST contents in a secure, browser-based environment.
Your Privacy Matters
This tool processes your PST files entirely within your browser using JavaScript. No files are uploaded to our servers, ensuring complete privacy and security for your email data.
