If you use Microsoft Outlook and have ever forgotten your PST file password, don't worry. I recently tried
GainTools PST Password Recovery Software, and it proved to be very useful. The software's specialty is that it can recover passwords from Outlook PST files of any size without any data loss. Its user interface (UI) is very simple, requiring no technical knowledge.
Key Features
Unlocks password-protected PST files in seconds.
Works with any MS Outlook version (e.g., 2019, 2016, 2013, etc.).
100% safe and virus-free software.
Test it for free with the demo version.
I used it to open my old Outlook backup, and it worked perfectly. If you've also forgotten your PST file password, be sure to give PST Password Recovery a try.
