How to Fix PST File Errors Without Losing Your Emails

Microsoft Outlook is one of the more commonly used email programs for personal and business use, and it keeps your emails, contacts, calendar entries, tasks, and notes in a file known as a PST. Yet, just like any other type of data file, PST files can become corrupted for a variety of reasons, which in turn makes your Outlook mailbox inaccessible. Fortunately, however, there are a number of methods by which you can correct PST file errors without losing the emails that are valuable to you.

This article will look at the usual reasons for PST file corruption, the symptoms you should be aware of, and the most effective ways to safely repair PST files.

What Causes PST File Errors?

If you understand the reasons why PST files become corrupted you will be able to avoid similar problems in the future. Among the more common causes are:

• Unexpected system shutdowns or power failures
• Malware or virus attacks
• Bad sectors on the hard drive
• Oversized PST files
• Improper Outlook shutdown
• Network interruptions while accessing PST files
• Hardware failures
• Outlook add-in conflicts

If any of these problems take place, Outlook will not be able to open the PST file or will show error messages.

Common Symptoms of a Corrupted PST File

If your PST file is damaged, you may notice one or more of these symptoms:

• Outlook crashes frequently.
• Error message: "Cannot open your default email folders."
• Outlook stops responding when you start it.
• Missing emails or folders.
• Send/Receive errors.
  The search function ceases to work.
  * You cannot open the PST file.

Failing to take note of these signs could lead to additional corruption and possibly to the loss of data.
