Reasons for the Inbox Repair Tool not Responding Issue
Though SCANPST or Inbox Repair Tool can repair PST files, several limitations prevent it from repairing the PST file or cause the program to stop responding. Below are some common reasons why SCANPST may stop responding while repairing the corrupt or damaged PST files:
- ScanPST.exe can repair small PST files. If you try to repair a large PST file, the tool may become unresponsive during the repair process.
- The tool can fix or repair minor errors and inconsistencies in the PST files. However, if the PST is severely corrupt or damaged, it may fail, hang, or stop responding while repairing the file.
- SCANPST may hang, freeze, or stop responding when the system is running low on resources, such as RAM, processor, or storage.
- Other applications, such as antivirus or other security apps, may lock the PST file during the scan and cause conflict, leading to unresponsive SCANPST.
- Sometimes, the file system on the drive where PST is stored or SCANPST (Inbox Repair Tool) is installed could be damaged, resulting in the SCANPST not responding issue.
