https://connect.mozilla.org/t5/discussions/can-t-open-an-old-outlook-pst-because-i-forgot-its-password/m-p/141574#M57773 <P><SPAN>I recently ran into the same problem with an old Outlook PST file that was protected by a password I couldn’t remember. After trying a few options, I came across SysInfoTools Outlook Password Recovery. It’s designed specifically for recovering or removing passwords from Outlook PST files, so it may be worth checking if you’re stuck with an inaccessible archive. Make sure you work on a copy of the PST first and review the software details before using it.</SPAN></P> Mon, 05 Oct 2026 12:08:53 GMT amitchandel07 2026-10-05T12:08:53Z https://connect.mozilla.org/t5/discussions/can-t-open-an-old-outlook-pst-because-i-forgot-its-password/m-p/133493#M53632 <P>I recently found an old Outlook PST backup that contains important emails, but I no longer remember the password. Since the data is valuable, I don't want to risk corruption by trying random methods. Is there a trusted utility that can safely remove the PST password and let me access the mailbox again? I came across the <A href="https://www.systoolsgroup.com/pst-password-remover/" target="_self"><STRONG>SysTools PST Password Remover Tool</STRONG></A> and would appreciate feedback from anyone who has used it to unlock password-protected PST files successfully.</P> Fri, 31 Jul 2026 12:36:26 GMT https://connect.mozilla.org/t5/discussions/can-t-open-an-old-outlook-pst-because-i-forgot-its-password/m-p/133493#M53632 Keth_charles 2026-07-31T12:36:26Z
