What Causes the Error in PST Files and How to Repair It?
Causes of PST file errors can include file corruption, oversize files, network connectivity issues, antivirus or firewall interference, and hardware failure. However, by taking the proper actions, you can avoid most of the common reasons for PST errors and ensure that your Outlook works smoothly. Here is the list of possible reasons, and their solutions:
PST File Corruption: The most common cause of PST errors in file corruption. PST files become corrupt due to various reasons, such as a sudden power outage, hard disk failure, virus attack, or improper system shutdown. When a PST file is corrupt, Outlook may fail to open it; and users may experience different PST file error messages.
Oversized PST File: Outlook has a default PST file size limit of 20 GB (in older versions) or 50 GB (in newer versions). When the PST file exceeds this limit, it can cause various issues, including PST errors.
Network Connectivity Issues: Outlook requires a stable internet connection to function correctly. If your internet connection is unstable or slow, you may experience various Outlook errors, including PST errors.
Antivirus or Firewall Interference: Sometimes; antivirus or firewall software can interfere with Outlook and cause PST errors. That can happen when the antivirus or firewall software incorrectly identifies Outlook as a threat and blocks it from accessing the PST files.
Hardware Failure: Hardware failure can also cause PST errors. It can happen when the hard disk or other storage media containing the PST file fails.
Besides the above list, sometimes it is very difficult to figure out the reason for PST file corruption. In such scenarios, the most apt way is to use a Magus Outlook PST converter and convert PST into EML. Later, you can open the .eml files into any of the desired formats.
PST errors can be frustrating and can cause significant disruptions to your work. However, with the right solutions, you can resolve these issues and get back to using Outlook efficiently.
