If you’ve lost the password to your old Outlook PST file, there’s no need to panic. I recently used GainTools PST Password Recovery and it proved quite useful. I’d forgotten the password to my old Microsoft Outlook PST file, but this tool easily unlocked the file without losing any data. The interface is very simple, & even new users can use it without any problems. If you’re looking for a safe and fast solution, this tool is a good choice.
