If you use Microsoft Outlook for email communication, you might be aware that the PST (Personal Storage Table) file which stores the messages and calendar events is prone to corruption. To deal with PST file corruption, Microsoft provides the Inbox Repair Tool for Outlook (Scanpst.exe) that can scan the structure of the damaged PST file and also repair it in most cases.
However, users often complain that Scanpst.exe freezes or fails while repairing Outlook PST files. If you are facing a similar issue with Scanpst.exe, this post is for you.
Before we look at the solutions to fix the Scanpst.exe freezing/fails issue, let’s first understand the reasons behind it.
Note - Close Outlook before proceeding to repair Outlook PST file by using Scanpst.exe.
Following are some of the reasons due to which Scanpst.exe may freeze/fails or not responding while repairing a PST file.
1. Update Scanpst.exe
Install all the updates available for Outlook client installed on your system. Scanpst.exe is a part of MS-Outlook installation. You can neither install nor update it independently. The only way you can update Scanpst.exe is by installing all the updates provided by Microsoft for the specific Outlook version you are using.
2. Reinstall Outlook program
If updating Outlook doesn’t resolve the issue, there’s a possibility that the installation of Outlook has become corrupt. In that case, reinstalling Outlook may resolve the issue.
3. Check the size of the PST file and try to reduce it
If you still find Scanpst.exe freezing while repairing Outlook PST file, you need to consider other factors. If you are using Outlook 2002 or earlier, check the size of the PST file.
If the size of the PST file is around 2G or more, you need to reduce the size of PST file as follows:
After reducing the size of PST file, run Scanpst.exe again to repair the PST file. In most cases, the Scanpst.exe would run without any errors and repair the PST file.
If you’ve failed to resolve the freezing issue with Scanpst.exe, you can try a specialized software such as Stellar Repair for Outlook to repair the corrupt PST file.
