Have you tried ScanPST.exe? It is a free tool offered by Microsoft to repair the corrupt PST file. However, ScanPST.exe cannot deal with the large corrupted PST file, or the file gets severely corrupted. In such cases, you can go for 3rd party tools [mostly paid]. These tools help you to repair the corrupt PST file without any file size limitations and as well as and you have the option to save the converted file in multiple file formats.
In case you are looking for the best 3rd Party tool to repair the corrupt PST file, I recommend Stellar Repair for Outlook. In the demo version, you can check the preview of your PST file data to check the efficiency of the software.
