Sometimes Scanpst.exe, also known as the Inbox Repair Tool, crashes on repairing Outlook PST files. There can be multiple reasons for this issue. In this blog post we will discuss reasons of the Scanpst.exe fails and how to troubleshoot this error. We will also illuminate your knowledge on how to repair corrupt file using Outlook PST Repair Software.

Introduction:

Microsoft Outlook uses two file formats—OST (Offline Storage Table) and PST (Personal Storage Table)—to store and manage mailbox data in the local system. The OST files allow you to access and work with your emails, calendar, contacts, and other mailbox items even when you are offline. On the other hand, the PST files are valuable for archiving old emails or creating backups of Outlook mailbox data. But these data files are prone to corruption that hampers the performance of Outlook application.

To deal with the corruption issues in the Outlook data files (PST) , Microsoft has provided an Inbox Repair Tool for Outlook (Scanpst.exe) to troubleshoot the errors. But some Outlook users frequently query “Scanpst.exe, Fails on Repairing Outlook PST Files.” If you are the one who is also encountering this issue, then this resource is just for you. In this post, we will shed light on how to repair corrupted PST files using Scanpst.exe and PST repair tool.

Understanding the Error:

In this section, we will discuss the primary reasons responsible for causing Scanpst.exe to freeze or become unresponsive during the process of repairing Outlook PST files. Below are some of the key reasons contributing to this issue:

  • Large PST File Size: This is one of the major reasons that causes this error. If the PST file size exceeds the prescribed size limit, it may cause Scanpst.exe or the Inbox Repair Tool to freeze during the repair process. If you are working on a system with the Outlook 2002 version or older, there is a strong possibility of you facing this error as older versions of Scanpst.exe cannot handle large PST files with a size of 2GB or more.
  • Severely Corrupted PST File: If the PST file is severely corrupted, then Scanpst.exe may fail to repair it completely. In this scenario, the probability of losing vital data is high.
