A PST file, or Personal Storage Table, is a crucial component of Outlook that stores various Outlook items such as emails, events, contacts, calendars, notes, reminders, and more. PST files allow you to work offline and synchronize changes with the Mail Exchange Server once an internet connection is restored.
However, PST files can become corrupt for various reasons, leading to errors like "PST is not a personal folder file" or "The PST file is corrupted and needs repair." This can result in Outlook being unable to open specific folders or send/receive emails.

How to Fix Outlook PST File?
There are two methods to repair PST files, depending on the severity of corruption. The first method involves using the built-in Outlook Inbox Repair tool, known as ScanPST.exe, for minor corruption issues (limited to 2GB). The second method utilizes a reliable PST Repair tool, such as Remo Repair PST, for larger files and severe corruption.
Method 1: Repair the PST File for Free
If your PST file is corrupt or inaccessible, start by using the SCANPST tool:
Step 1: Locate and Repair Using ScanPST
- Locate the ScanPST tool on your Windows computer (Location of the Scan PST tool depends on your Outlook version).
- Outlook 2021: C:\Program Files\Microsoft Office\root\Office16\
- Outlook 2019: C:\Program Files\Microsoft Office\root\Office16\
- Outlook 2016: C:\Program Files (x86)\Microsoft Office\root\Office16
- Outlook 2013: C:\Program Files (x86)\Microsoft Office\Office15
- Outlook 2010: C:\Program Files (x86)\Microsoft Office\Office14
- Outlook 2007: C:\Program Files (x86)\Microsoft Office\Office12
- Open SCANPST.EXE by double-clicking it.
- Click the Browse button to select the corrupt Outlook PST file.
- Click Start to initiate the scanning process.
- If corruption is found, select "Make a backup of scanned file before repairing" for safety.
- Click Repair to start fixing the PST file.
Note: ScanPST may need to be run multiple times and cannot repair severely corrupted PST files. In such cases, consider using the Remo Repair PST tool.
Step 2: Recover Additional Outlook Items
After using ScanPST to repair minor PST file corruption, you can access missing or deleted items by following these steps:
- In the Folder List, locate the "Recovered Personal Folders" folder created after repairing the PST file. It contains default folders like Calendar, Contacts, Deleted Items, Inbox, Journal, Notes, Outbox, Sent Items, and Tasks.
- If these recovered folders are empty, look for the "Lost and Found" folder, which contains the recovered items. However, the recovered items may not be as organized as they were originally. To address this, you can create a new Outlook PST file:
Step 3: Create a New PST File
Follow the below steps to create a new PST file:
- Open Outlook and go to File > Info.
- Click on Account Settings and then Account Settings again.
- Select Data Files and click the Add tab.
- Enter your preferred PST file name in the File Name field.
- Click OK to create a new PST file.
Note: Creating a new PST file allows you to import recovered items from the Lost and Found folder to your desired location. Simply drag the recovered Outlook items from Lost and Found or Recovered Personal Folders to your specified location and delete the Lost and Found/Recovered Personal Folders.
Bonus Tip: Recover Using .bak Files
A .bak file is a backup created by SCANPST during the PST file repair process. To recover additional Outlook items that cannot be restored by ScanPST alone, follow these steps:
- Go to the PST file location and locate the .bak file.
- Make a copy of the .bak file.
- Rename the .bak file extension to .pst (e.g., rename outlook.bak to Outlook.pst).
- Import the .pst file into Outlook using the Import/Export wizard.
Note: In some cases, even this method of recovering Outlook items might not work effectively if the severity of PST file corruption is beyond repair.
