What is PST File?

A PST file is a personal storage table, which is used to store Outlook data such as emails, contacts, calendars, and more. It acts as the main repository for all your MS Outlook information and can be accessed by the user at any time.

When you create an email account in Microsoft Outlook or use it to connect with Exchange Server, a PST file gets created on your local system. This file stores all your important emails along with attachments that are received or sent through the application.

The size of a PST file can grow rapidly if you receive large numbers of emails every day. In some cases, this may lead to corruption or damage due to various reasons such as virus attacks, sudden power failure during synchronization process and hardware failures.

It’s important to maintain regular backups of your PST files so that you don’t lose all your important information in case of accidental deletion or corruption. Moreover, using reliable tools like Stellar PST Repair software can help you recover damaged files without losing critical data stored within them.

Reasons for PST File Corruption

There are various reasons why a PST file can become corrupted. One of the most common causes is due to oversized or bloated files that have exceeded their storage capacity.

Another reason for corruption could be due to sudden power failures, abrupt system shutdowns, or hardware failure. These issues can interrupt the writing process and lead to data loss or corruption.

Malware attacks can also cause damage to PST files by corrupting them or deleting important data altogether. This is especially true if your computer’s security software is outdated or not functioning correctly.

Human error such as accidentally deleting items from the mailbox, transferring emails between folders incorrectly, and improperly closing Outlook may all contribute to PST file corruption.

It’s essential always to keep backups of your data and regularly scan for viruses/malware on your system. By doing this, you’ll significantly reduce the risk of losing critical information in case of any unforeseen circumstances.

In-built Repair Utility- ScanPST.exe

Every Microsoft Outlook user is aware of the ScanPST.exe utility, which comes as an in-built repair tool for fixing minor issues with PST files. This free software can easily diagnose and repair corruption issues within your PST file.

ScanPST.exe scans through the header section and mailbox data of your damaged PST file to detect any errors that may have occurred due to sudden shutdowns or system failures. It then repairs those errors by either removing corrupted data or restoring it from a backup.

Although ScanPST.exe can prove helpful in repairing small-sized PST files, it may not be able to handle more extensive damage with larger files. It also lacks features such as previewing repaired items before saving them.

If you’re dealing with significant corruption or looking for advanced features like selective recovery, then using a professional tool like Stellar Outlook Repair would be beneficial. However, if you’re confident that your issue is minor and limited only to the header area, then trying out ScanPST.exe could save you time and money.
