If you've accidentally deleted important emails from Outlook, recovering your PST file can be straightforward with the right approach. The PST file, which [stores your Outlook data](https://todayfixtech.com/backup-data-microsoft-365/), can become corrupted for various reasons, but with these steps, you can retrieve your lost emails effectively. This guide will walk you through common causes of PST file corruption, recovery methods, and preventive measures for future data loss.

## What causes PST file corruption?

PST file corruption can occur due to several common factors. An unexpected shutdown of your computer might interrupt the writing process to the PST file, leading to corruption. Exceeding the maximum size limit for PST files, especially in older versions of Outlook where the limit is 2GB, is another frequent cause. Hardware failures, disk errors, and malware attacks can also contribute to corruption. Being aware of these factors can help you avoid potential data loss.

## How to recover PST files using Outlook's built-in tool

Outlook includes a built-in utility called the Inbox Repair Tool (ScanPST) that can help you fix corrupted PST files. Here's how to use it:

### Prerequisites

- Microsoft Outlook installed on your computer.
- The location of your PST file.

### Steps

1. Locate the ScanPST tool. It’s usually found in the Outlook installation directory. The path is often:

```text
C:\Program Files (x86)\Microsoft Office\root\OfficeXX\SCANPST.EXE
```

1. Open ScanPST by double-clicking it.
2. Click on the "Browse" button and navigate to the PST file you want to repair.
3. Click on "Start" to begin the scanning process.
4. If the tool finds errors, it will prompt you to repair them. Click "Repair" to fix the issues.
5. Once the repair is complete, open Outlook to check if your emails have been restored.

### How to verify if recovery was successful

After recovering your PST file, ensure that all necessary emails and data have been restored. Here’s how to check:

1. Open Outlook and navigate to the folders where your emails were previously stored.
2. Check the "Deleted Items" folder to see if any emails have been restored there.
3. Use the "Search" function in Outlook to look for specific emails or keywords you remember.
4. Review any contacts, calendar events, and tasks to confirm they are intact.

If you find that some items are still missing, you may need to consider additional recovery options or consult a professional.

## Using third-party software for recovery

If the built-in tool doesn’t resolve the issue or if the corruption is severe, you may need to consider third-party recovery software. Several reliable options are available, each with its pros and cons.

### Considerations

- Check reviews and user feedback before purchasing any software.
- Most tools offer a free trial version, allowing you to see if they can detect your issues before making a purchase.
