Method 1: Repair PST file using the ScanPST.exe tool
If your PST file is corrupt or inaccessible, the first thing to do is to utilize the SCANPST tool. This inbox repair tool is designed to solve all the minor corruption associated with the Outlook data file (.pst) with ease. However, it is recommended to take a copy of your PST file before you start fixing it.
A) Steps to Repair PST file using ScanPST tool:
- Locate the ScanPST tool on your Windows computer. You can make use of the following ScanPST location based on your Outlook version.
- 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 on it to start repairing corrupt PST file.

- Click the Browse button and select the corrupt Outlook PST file that you want to repair.

- Click the Start button. Now, the inbox repair tool will start scanning the PST file to find any corruption or error in the Outlook data file (.pst).
- Once the SCANPST tool finds any corruption in the PST file, select Make a backup of scanned file before repairing option to create a backup copy. This will ensure the safety of your corrupt Outlook data file.
- Now, click the Repair button to start fixing PST file corruption.
The major disadvantage of using the ScanPST is you need to run it multiple times to repair PST file. And also it cannot repair the severely corrupted Outlook PST file. During such instances, you can make use of the Remo Repair PST tool.
B) Recover Lost and Found folder- After Repairing PST file using ScanPST
Once the ScanPST repairs minor Outlook PST file corruption, open your Microsoft Outlook account (If you use multiple profiles, then open Outlook with the repaired PST file). And follow the steps to access missing or deleted emails, contacts, reminders, and other Outlook folders.
In Folder List, locate the Recovered Personal Folders, a folder that gets created after repairing the PST file. And it contains all your default folders like Calendar, Contacts, Deleted Items, Inbox, Journal, Notes, Outbox, Sent Items, and Tasks.
If you find the above recovered personal folders empty, then look for the Lost and Found folder. It contains all the recovered items. However, the recovered Outlook items cannot be placed in their original structure. To overcome this issue, you can create a new Outlook PST file.
Steps to create a new PST file:
- Open Outlook and go to File > Info.
- Click on Account Settings and then, Account Settings.
- Select the Data Files and click on Add tab.
- In the File Name field, enter the PST file name of your choice.
- Click OK. This will create a new PST file.
Note: Creating a new PST file, will help you import the recovered items from the Lost and Found folder to your desired path. In your new Outlook PST file, you can just drag the recovered Outlook items from Lost and Found or Recovered Personal Folders to your specified location. And later, you can delete the Lost and Found/ Recovered Personal Folders.
C) Recover Additional Outlook items from Repaired PST file using .bak file
A .bak file is a backup file created by the SCANPST tool during the PST file repairing process with the same name of the corrupt .pst file under the same location or folder but with a .bak extension. With the help of this backup file, you can recover the extra Outlook items that cannot be restored even after using the inbox repair tool.
Steps to Recover Additional Outlook items using .bak file
Go to the PST file location or folder > locate .bak file > Make a copy of the .bak file > Rename the .bak file extension to .pst file (for example outlook.bak to Outlook.pst) > Import the .pst file in your Outlook using 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.
