Best PST Password Remover Tool to Unlock Secured Outlook Files
Microsoft Outlook is used to manage email, calendar, contacts, and tasks. When we create a backup of data in Outlook, it is saved in PST (Personal Storage Table) format. Many times, users password-protect their PST file so that no unauthorized person can access the data.
But if you forget the password, it can cause trouble. In this blog, we will tell you how to recover the PST file password manually and which third-party tools can help if the manual method does not work.
Why is PST password recovery needed?
Forgot password
Need to open an old backup file
Access a former employee’s email data
Need access after changing Outlook profile
1. Manual Method: How to Recover PST Password (Using Microsoft Utility)
Microsoft previously provided a free tool called PST19UPG.exe and PST Password Recovery Tool (often referred to as “pst19upg” and “PstPassword”). Although it has been removed from the official site, the tool can be found on some old websites or backups.
Note: This method only works on older ANSI PST files (Outlook 2002 and earlier). It will not work on newer Unicode PST files (Outlook 2003 and later).
Step-by-step:
Create a backup of your password-protected PST file.
Download Microsoft’s PST Password Recovery Tool.
Run the tool and select your PST file from the “Open” button.
It will show you the password or remove the password.
Now you can open the file without a password in Outlook.
2. Recover PST Password with Third-Party Tools
If your PST file is new (Unicode format) or the manual method is not available, you will have to use third-party software. These tools can safely remove the password and give the result in a few seconds.
