what version of Outlook are you running.  It maybe the 20GB limit issue.  There is a registry hack that you can apply that will increase the max size to 50 GB.
Once you have this setting applied try to open the PST without doing the PSTSCAN.

Hello, Syed
 Your file size is too big it cannot be scanned and resolved through ScanPST. exe. I still would like to suggest you try manual method once again.
Check out this blog to repair your PST files with SCanPST.exe. Though chances are less but who knows at least give a try.
If could not do with the manual trick then you to go for some PST recovery Tool. No doubt there are lots of entrusted vendors. It's you who have to decide we can just suggest you.  Try the free version of all the software you have short-listed then only for final purchase.
As far as my experience I would suggest you PST file repair Tool. If you are not still sure you can give a try to this utility.
Hope thIs information helps you.

There are a lot of online resources discussing about how to recovering corrupt or damaged PST files.

First, the Microsoft offical tool scanpst, also called Inbox Repair Tool, can repair the PST file, you can refer the following articles:


Second, as you have tried that scanpst doesn't work ,  there are many third-party Outlook recovery tools you can try. Nearly all these tools provide a free trial so you can try first to see if a tool works before purchase it.

Good luck!
