PST files are used to store Microsoft Outlook email and your other data like contacts, calendar, tasks etc. If Outlook fails to open or gives error messages when you try to access your mail, chances are that your PST file is corrupted. Microsoft provides a built in utility called Inbox repair tool or Scanpst.exe, which can deal with some of these corruption issues. Unfortunately, Scanpst.exe is not a very powerful tool and often fails to fix corrupt PST files and the major drawbacks of this tool are as follows:
Whenever your PST file gets corrupted, you usually use Scanpst.exe tool to repair the PST file, but sometimes even when you use it, you may get an error message like ”Fatal Error 80040900” and the corrupted PST file remains same. This kind of error generally occurs when your PST file is oversized i.e. when its size is more than 2GB
Also sometimes when you use scanpst.exe, you may receive an error such as “An error has occurred which caused the scan to be stopped. No changes have been made to the scanned file”, which is a severe problem because the PST file scan was interrupted and your corrupt PST file is still the same and you get errors in PST or if you want to repair PST file not responding use Inbox Repair Tool.
