If your PST file becomes unresponsive, freezes, or hangs, it may be damaged or corrupted. you will notice several issues like Something Went Wrong with One of your Data Files Outlook, Send receive error, etc
There are several ways to make the situation worse. However, with the right methods, we can repair your Outlook PST file and restore all its data.
How do I know if my PST File is Corrupted?
1. Read the error message description
You can look up the error number/ name on the internet to learn about its effects, causes, and more.

If a PST does not work on any system, the file itself is the problem and might be corrupt.
3. Use ScanPST
You can use ScanPST to scan your PST file for any signs of corruption or damage.
If you believe that your PST file needs to be repaired, you can try out the DIY methods given in the section below-
Is there a free way to repair a PST file?
You can repair corrupt PST file(s) in two ways. One by using a specialized PST file repair software, which can fix severely corrupt or extremely damaged Outlook PST files. The other way is to use an in-built tool called ScanPST, which is a free tool but can only fix minor issues and corruption in the Outlook data files.
What is the best tool for repairing Outlook PST files?
ScanPST first, always. It ships free with every version of Outlook, including Outlook 365, and it is the right starting point even though it only handles minor corruption. If ScanPST finishes with no errors but your inbox is still missing messages or folders, that is your sign the damage is past what it can repair.
From there, the right tool depends on how bad the damage is and whether you can afford to lose anything. SFWare PST Repair Tool is built for exactly the files ScanPST gives up on: severely corrupted PST files, oversized files that choke ScanPST’s repair process, and files where the folder structure itself is broken rather than just a few messages. It scans the file independently of Outlook’s own repair logic, which is why it can often recover data ScanPST reports as unfixable.
There is no single tool that is best for every situation. A lightly corrupted 1.5 GB file is a different problem than a 40 GB PST that will not mount at all.

Conclusion
Thank you for your time. When faced with a technical error, I urge my readers to always read about the situation they are in and pursue it with caution. More often than not, a user makes things worse by trying to tamper or solve the issue on their own which in turn makes things worse.
Can a corrupt file be repaired?
Most of the time, yes. A PST file gets corrupted at the header, the folder index, or somewhere in the middle of the data stream, and each of those failure points behaves differently. Header damage is usually the easiest to fix because ScanPST and most repair tools can rebuild it from the surrounding structure. Damage scattered through the body of the file, the kind you get from a drive that is failing or a PST that crossed the 2 GB mark on an older ANSI format, is harder.
There is a point past which no tool, ours included, can pull everything back. If the file will not even open in a hex editor without throwing garbage, or if large sections of it are zeroed out from a bad sector, you will get partial recovery at best. I have seen PST files come back with every folder intact except one, usually Sent Items, because that is the folder Outlook was writing to when the crash happened. Repair almost always means partial repair. Treat 100 percent recovery as the exception, not the expectation.
