When you use Outlook Inbox Repair Tool (Scanpst.exe) to repair a damaged or corrupted Outlook personal folders(PST) file, instead of performing the repair task, the tool hangs endlessly and does not respond to user commands. If you open Windows Task Manager, you will find the application’s status is “Not Responding”. If you shut down the application abnormally and restart it to re-repair the same file, you will always get the same results.

Precise Explanation:

The corruption or damage of the PST file is very heavy and complex. When Inbox Repair Tool (Scanpst) tries to repair the file, it will run into dead loops endlessly and cannot repair the file any more.

You should use DataNumen Outlook Repair to repair the corrupt PST file. With sophisticated programming and algorithm methodology, DataNumen Outlook Repair will always recover most of the recoverable data form the corrupt PST file, so it is the best Outlook recovery tool in the market.
