Are you having trouble with your PST files? Follow along as we explore a few tools to repair Outlook data.

Outlook is one of the premier emailing services used by many students and professionals around the globe. It's quick and convenient. All these advantages make it one of the prioritized options among institutions and professional environments.


However, the problem occurs when the PST, the extension file saved by Outlook, gets corrupted or lost. That's when PST repair tools are an extraordinary program for many users. So, which are the best ones? Today, we'll look at the top 5 free PST repair tools and analyze the reason behind this problem. So, let's get started.

Common Causes of PST Files Corruption

PST or personal storage table is the file extension code for an Outlook file. While it's mainly found in Outlook, other Microsoft programs also use it to store necessary information, such as calendar events, contacts, emails, and messages.

However, when the PST file is corrupted, people often end up losing all the aforementioned data, such as messages, calendars, etc. So, what causes this sort of corruption? What are some of the common reasons people lose PST files and, consequently, their essential information?

Let's divide them into two categories:

PST File Corruption Due to Hardware Reasons

The first and perhaps the most common cause of PST data corruption is caused by hardware failure. This can include three main types of error and losses involving hardware, such as:

  • Network issues
  • Bad Sectors on Hard Drive
  • Sudden Power Failure

Network issues can cause the computer to misread or corrupt the file if the connection is interrupted. While sudden power failure will stop the read/write process, which will end up ruining all the data within that PST file.

Lastly, a bad sector on a storage device is bound to cause such problems. This will cause not only Outlook to not work correctly but also corrupt PST files beyond readability.

PST File Corruption Due to Software Reasons

The second type of PST file corruption can be caused by software issues. These issues can corrupt PST files; however, no hardware is involved. So, what exactly causes this? It's likely to be two reasons:

  • Malicious Software
  • File System Recovery

A malicious virus attack can ruin every type of file, so there's no wonder it can also affect PST files. On the other hand, poorly recovered system file also causes this problem. The two significant reasons PST files become unreadable could be these two events.  

Tip: Recover Lost PST Files for Free (Recommend)

Even if the PST file is beyond readable, that doesn't mean it's beyond recovery. So, how do you recover corrupted PST files if they have essential information? Moreover, how do you recover them for free?

The answer is using a professional recovery tool—preferably a third-party one. One of the best tools to do that is EaseUS Data Recovery Wizard. What makes it the top contender for recovering lost files? Let's find out.
