Every email application, including Outlook, saves its data in a file format. Outlook is widely regarded as one of the most popular email applications in the world. Outlook’s mailbox data is stored in the PST file format, which stands for Personal Storage Table. Furthermore, this file format is prone to corruption.

Many Outlook users are now dissatisfied as a result of the corruption of the Outlook data file, and if you are one of them, then this blog will address how to resolve the corruption of the Outlook data file (PST). Along with the fix provided in this article, we will also discuss how to prevent our PST file from becoming damaged.

But, before we get into the procedure, let’s go over the causes of Microsoft Outlook data file corruption.

The Cause of Outlook Data File Corruption

One of the most common causes of Outlook profile corruption is a damaged PST file. Because Outlook frequently crashes as a result of a damaged PST. As a result, it is critical to correct the corruption issue in Outlook. Another problem is that when the PST file grows big, users experience profile corruption. The remaining factors are also listed here.

  • Outlook suddenly terminated.
  • Interference or delays during Outlook data transmission
  • Vague Outlook installation or profile configuration

Now that we’ve established the causes, let’s look at how to determine whether or not your Outlook data is damaged.

Note: If you have a corruption issue, you may have issues and bugs such as Outlook, not opening, PST files not found, and Outlook stuck on a blue screen or loading profile screen, among other things.

How to Prevent Outlook Data File Corruption

In this part, we will explore various strategies that can assist you in preserving Outlook data files that have become damaged.

#Tip 1: Disable Outlook Force Termination.

Outlook offers a set of instructions for closing the software. However, many people force the Outlook application to close by clicking on the red close icon. However, as previously said, this approach will wreak havoc on your Outlook data file. As a result, always close Outlook by following the instructions below:

1. To begin, select File from the top menu bar.

2. Then, to exit the Outlook software, click the Exit button.

#Tip 2: Avoid Forced System Termination.

There are times when you must violently shut down your machine. However, this will have an impact not only on the system hard disc but also on the software that was running on your computer before shutting it down. Now, if you are working on Outlook, do not violently shut down your machine.

#Tip 3: Keep the Mailbox Size Consistent

If an oversized Outlook PST file is the cause of Outlook data file corruption, consider cleaning your Outlook mailbox on a regular basis. Because trash files, duplicate data items, or huge attachments may quickly overflow your Outlook mailbox.
