5 Min. Read

Researchers estimate that billions of emails are sent worldwide every day, most commonly with Microsoft Outlook’s email software. While email has been around for decades, it’s all too common for emails to go missing or become corrupted, even in 2023. Unfortunately, users might face the risk of missing data and corruption of PST files for numerous reasons, along with virus attacks.

In this guide, we will show you 3 methods that you can use to fix corrupted PST files in Microsoft Outlook.


In today’s digital era, email has become an essential communication tool for individuals and businesses alike. Microsoft Outlook is a popular email client that stores its data in Personal Storage Table (PST) files. However, these files can sometimes get corrupted, leading to various issues such as data loss, inability to access emails or system crashes.

With many of the world’s most important files being delivered over email, users need a way to access vital emails safely and efficiently. The best way to access essential emails accompanied with attachments, personal folders, contacts, notes, etc., is to use Microsoft Outlook Inbox Repair Tool, the Microsoft Outlook Fix PST Software for PC, or Online Service for Recovering Outlook Data Files for any other platforms and mobile devices.

These tools are designed for Outlook Data Files (PST and OST) in Outlook for Microsoft 365, Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010, and Outlook 2007.

If you’re facing such problems, don’t worry! In this article, we will explore three effective methods to fix corrupted PST files and regain access to your valuable email data.

Method #1: PST File Recovery with the Inbox Repair Tool

If you can’t open your Outlook data file or suspect that the email file is damaged, you can use the Inbox Repair tool (SCANPST.EXE) to diagnose and repair errors in your Outlook data file.

This method works best in the following situations:

  • Outlook can’t open your data file.
  • Outlook can’t open the set of folders.
  • Outlook data files may be damaged.

The Inbox Repair tool will not connect or analyze any data in an Outlook Exchange email box. Instead, the tool only checks for errors (corruption) within the file. If any errors are found, the tool allows you to fix those errors.

You may need to locate your Outlook Data Files in Outlook before repairing corrupt PST files. Here’s how you can do this:

1) Within Microsoft Outlook, select File, then Account Settings, and click on Account Settings.
2) Next, click the Data Files tab.
3) All Outlook Data Files (.PST) and Offline Data Files (.OST) will be listed, along with the account name associated with the files.

To repair an Outlook (.PST) file, close Microsoft Outlook first, and then navigate to one of the following locations based on the Outlook versions that you have:

> For Outlook 2019: C:\Program Files\Microsoft Office\root\Office16
> For Outlook 2016: C:\Program Files\Microsoft Office\root\Office16
> For Outlook 2013: C:\Program Files\Microsoft Office\Office15
> For Outlook 2010: C:\Program Files\Microsoft Office\Office14
> For Outlook 2007: C:\Program Files\Microsoft Office\Office12

Next, find and launch the SCANPST.EXE tool:

Once the process is completed, start Outlook with the profile associated with the Outlook Data File you just repaired.

Please note that during the repair process, a backup file is created. If you would like to modify the default name or location of the backup file, you can enter a new name or click “Browse” to locate the desired file.

The Inbox Repair tool creates a backup copy of the original file in the same folder, with the same name but with a .bak extension. If you want to retrieve items from the backup (.bak) file, you should duplicate the backup file and rename it with the bak.pst extension. For example, you can rename it as

Next, open Microsoft Outlook and import the bak (.PST) File. Go to FileOpen & ExportImport/ExportImport from another program or File as shown in the figure below.

You might have to run the Inbox Repair (SCANPST.EXE) tool numerous times to repair your Outlook Data File. If an object was corrupted or erased permanently, it might not be possible to retrieve it.
