I recently tried to access an old Outlook PST file, but I have forgotten the password that was set on it a long time ago. I no longer have any way to remember or retrieve that password manually. The file contains important emails and contacts that I need access to urgently. Can someone please guide me on how to open or unlock a PST file when the password is forgotten? Are there any safe and effective tools or methods available that do not damage the data inside the file?
