Cause

This error occurs when the specified PST file cannot be accessed due to disk errors or insufficient permissions. Common reasons include:

• The file is being used by another application.
• Insufficient permissions to access the file.
• Disk-related issues such as file system corruption or hardware failure.
• Additionally, the PST file itself may be corrupted.

Solution

• To resolve this issue, follow these steps:
  
  1. Check file permissions: Ensure that the PST file and its containing directory have the correct permissions for your user account.
     
     • Navigate to the directory containing the PST file.
     • Right-click on the PST file and select "Properties."
     • Go to the "Security" tab and ensure that your user account has "Full control" permissions. If not, click "Edit" and adjust the permissions accordingly.
     • Repeat this process for the containing directory if necessary.
  2. Ensure the file is not in use: Make sure the PST file is not currently being used by another application.
     
     • Close Outlook and any other applications that might be using the PST file.
     • Check the Task Manager (Ctrl + Shift + Esc) for any instances of Outlook or other related processes and end them if necessary.
  3. Run scanpst.exe: Try using the Inbox Repair Tool (scanpst.exe) to repair the PST file. This tool is provided by Microsoft and can fix corruption issues in PST files.
     
     • Close Outlook and any other applications that might be using the PST file.
     • Find the scanpst.exe tool on your computer. Its location will depend on your version of Outlook and Windows.
     • Open scanpst.exe and browse to the location of the PST file you want to repair.
     • Click "Start" to begin the repair process. Follow the on-screen instructions to complete the repair.
       
  4. Move the PST file to a different location: If permission and disk issues persist, try moving the PST file to a different location and updating Outlook to point to the new location.
     
     • Copy the PST file to a different directory (e.g., C:\PSTFiles\).
