Errors Encountered When Scanpst.exe Fails to Respond & Repair

There are many errors related to scanpst not working. Whether it does not open or freezes during the process, it simply is headache-inducing. Below are some errors when ScanPST fails to responds and repairs:

1. Scanpst.exe entry point not found:-

This error generally occurs if the Outlook is damaged or not installed properly. It may also occur if Outlook is not capable enough to deal with the file specified in the error stating that is missing or having some issues. In that case, a third-party tool would be a suggestion.

2. “Scanpst.exe fails with system fatal error: 80040818”

This is the most frustrating error that is observed during the repair process. If scanpst.exe tool gets this error then it will not be able to repair the damaged PST file. Because due to this error Scanpst.exe freezes completely and does not respond.
