  1. Great little tool for resetting a password from years ago that the old Windows system “remembered” but no one else did! Thank you so much!

  2. chrome flagged it as malicious and both my virus scanners flagged it as malicious. so i installed used it in Acronis Try & Decide mode and I was able to crack my pst files and to unlock them. great tool. 15 thumbs up

  3. Worked like a dream. Accidentally set a password on outlook and I had no idea what I had set it as. This got me right back in no problems.

  4. Thank You! Thank You! Thank You!

    You have no idea how tense I was. All my mails since 2007 were in that .pst file and I lost the password because I checked that “Save Password in your list” option in Outlook last year.

    I hve no words to show my gratitude Mr. Carl Norton. You are a life saver for me. 🙂

  5. This tool worked like Magic and provided 3 alternative passwords using which I could open my PST in outlook.
    Excellent and very happy.
    Many many thanks to Mr. Carl Norton.

  6. Microsoft: “IMPORTANT Passwords cannot be reset or recovered if lost. If you forget your password, Microsoft cannot retrieve it.”
    but it’s work! best tool!

  10. How do I find account settings if I cannot get into Outlook?
    1.Open the Account Settings window:
    ◾Office 2010: …….. How do I do this? Is there a command line to start Office 2010?
