Trouble Opening PST File? Learn How to Access Your Emails

If you’re struggling to open a PST file, you’re not alone. Many users face issues when trying to access their Outlook emails, especially when the file is corrupted, too large, or not supported in their current email client. Fortunately, there are several ways to open and recover emails from a PST file. In this blog, we’ll explore the best methods, including manual techniques and third-party tools like Aryson PST Viewer.

What is a PST File?

A PST (Personal Storage Table) file is a data storage format used by Microsoft Outlook to save emails, contacts, calendars, and other mailbox items locally. While PST files are useful for backups and offline access, they can sometimes become inaccessible due to corruption, size limitations, or compatibility issues.

Common Reasons for PST File Opening Errors

Before diving into solutions, let’s understand why PST files may fail to open:

1. File Corruption – Sudden Outlook crashes, improper shutdowns, or virus attacks can corrupt PST files.
2. Oversized PST File – Outlook has a size limit for PST files (usually 50GB for newer versions). Exceeding this limit can cause errors.
3. Outlook Version Mismatch – Older PST files may not open in newer Outlook versions and vice versa.
4. Password Protection – If the PST file is password-protected and you forget the password, you won’t be able to access it.
5. Storage Media Errors – If the PST file is stored on a damaged hard drive or external device, it may become unreadable.

Best Ways to Open and Access PST Files

Method 1: Use Microsoft Outlook’s Built-In Repair Tool (ScanPST.exe)

Microsoft provides an inbox repair tool called ScanPST.exe (or SCANOST.exe for OST files) to fix minor PST file corruption.

Steps to Use ScanPST.exe:

1. Locate the tool (usually found in the Outlook installation directory).
2. Run ScanPST.exe and browse for the corrupted PST file.
3. Click Start to scan and repair errors.
4. After repair, open Outlook and import the fixed PST file.

Limitation: This method may not recover severely corrupted PST files.

Method 2: Create a New PST File and Import Data

If the PST file is partially accessible, you can export data to a new PST file.

Steps to Export PST Data in Outlook:

1. Open Outlook and go to File > Open & Export > Import/Export.
2. Select Export to a file and choose Outlook Data File (.pst).
3. Select the folders you want to export and save them to a new PST file.
