The problem with Windows 11/10 is that the permission changes for the PST file are not properly applied. This can be solved by changing the file permission. To access your PST file, first, select File Explorer from the Start button.
Browse to the file location as shown in the error. For example, if the error message says the file is in C:\Users\\Documents\Outlook Files, then browse to that folder.
When you’re done, right-click the file and choose Properties. In the Properties window, select the Security tab and hit the Edit button. In the Permissions window, select your user account and click the Allow box next to Full control.
Click OK in all dialog boxes to close them and gain Full Control permissions for the Administrators and System users. After you have completed all the steps, restart your computer. You should now be able to access the PST file or start Outlook, even if you have upgraded to Windows 10.
When you’re finished, restart your computer. If you can’t access the PST file, it’s probably because the file is corrupted. Once everything is finished, restart your computer. If you’re encountering problems with your PST file, Microsoft offers a free repair tool called Inbox Repair Tool. This tool can fix Outlook PST files with ease.
