Reasons to Restore Outlook PST File

There are plenty of reasons to restore the Outlook PST data file. We have listed some of them in this section:

  • Critical database pointers were severed due to a system crash or a hardware glitch, causing PST file corruption. 
  • If the PST file reaches its size limit, becoming unfunctional. This caused high latency and eventual metadata instability.
  • A user-initiated permanent deletion event has emptied the trash folder, too, necessitating restoring from a backup. 
  • The user got a new laptop and needs to import important legacy PST file emails to maintain continuity.
  • A malware attack has messed up your Outlook PST files, requiring a restore from an offline backup.  

Due to the above-stated reasons, users want to restore the PST file in the Outlook application. Now, move further towards the next section, in which we are going to learn the best possible ways to restore the Microsoft Outlook PST data file.

Top Methods to Restore PST File in Outlook

Let us now understand each of the methods in more detail in a step-by-step manner. There are two ways by which users can restore their PST file, which is corrupted or damaged. 

Method 01: Restore Outlook PST File Using ScanPST

Microsoft Outlook provides a built-in ScanPST.exe (Inbox Repair Tool) to restore data from a corrupted PST file. But it only restores minor inconsistencies. 

The following are the steps to begin the process:

  1. Start by closing Outlook completely. Also, check the Task Manager.
  2. Then, locate and open the ScanPST.exe.
  3. Head to Browse and find the desired PST file.
  4. Click on the Start button to scan the corrupted PST file.
  5. After that, press the Repair option and then reopen Outlook.

Limitations: This approach only fixes minor or moderate corruption. It also does not recover the permanently deleted items. 

Method 02: Restore Outlook Backup PST File 

While repairing the PST file using ScanPST.exe, MS Outlook creates a backup file named .bak. This backup file can be further converted into a usable PST file. 

Use the following instructions to initiate the restoration:

  1. First, close Outlook completely.
  2. Then, head to the location where your PST file is stored.
  3. After that, right-click on the .bak file, select Copy, and paste it into the same folder.
  4. Again, right-click on this file and rename the extension from .bak to .pst.
  5. Click on Enter and launch the MS Outlook application.
  6. Go to File > Open & Export > Import/Export > Open Outlook Data File.
  7. Next, select the renamed PST file.

Limitations: For using this method, you need a .bak file, which will be created only during the ScanPST operation. Also, it does not help users to fix major or severe file corruption. 

Using the above process, you can successfully restore a PST file in the Outlook application. But this process is lengthy due to users searching for an instant way to recover their PST files. Hence, in the upcoming section, we are going to introduce the expert’s solution for the same.
