I recently found an old backup PST file from my Outlook archive that I urgently need to access. Unfortunately, the file is password-protected, and I can not remember the password anymore. Since this PST file contains important old emails and attachments, I do not want to risk data loss or corruption while trying to unlock it. Has anyone successfully used a PST password remover tool in such cases? If yes, could you suggest a safe and reliable solution that works on large PST files without causing errors?
