I recently found some old PST files that were created in an older version of Outlook. The problem is that these files are password-protected, and I no longer remember the passwords. I need to access the emails, contacts, and attachments stored inside them for some important work. I tried opening them directly in Outlook, but it keeps asking for a password that I can not recall. Is there any reliable method or tool that can help me decrypt and unlock these PST files without losing any data?
