Remove Outlook PST File Password in Just a Few Clicks
This blog is for you if you're having trouble removing your PST file in Microsoft Outlook and are getting the "Invalid PST Password" issue. Here, we'll discuss two primary approaches to fixing this problem: a third-party tool (if you've forgotten the password) and a manual approach (if you know the password).
What's the problem?
If a PST (Personal Storage Table) file has a password and Outlook is asking for access, but the password isn't working, you might encounter an "Invalid PST Password" or similar message.
According to Microsoft, if you forget your PST file's password, it's impossible to recover it from Outlook.
So it will be an issue if the password is invalid or you cannot recall it.
Part 1: Manually Resolve (If You Know the Password)
This method works if you've previously password-protected your PST file & you know your current password.
Step-by-Step
Open Outlook.
Choose File > Account Settings > Account Settings.
To retrieve or remove a PST file, click on the "Data Files" tab.
Press the “Settings” (or “Properties”) button.
Click the “Change Password…” button.
Enter the old password here, then the new password, or if you want to remove the password, leave both the new and confirmation boxes blank and click OK.
Restart Outlook and check if the PST file can be accessed or deleted.
Notes
This manual method will not work if you have forgotten the password.
Entering the wrong password will cause Outlook to refuse to open the file. Microsoft has clarified that “if you have forgotten the password, Microsoft cannot restore it.”
Part 2: Solutions with Third-Party Tools (When You Forgot Your Password)
Suitable outside programs can assist if Outlook refuses to recognize your password or you are unable to recall it.
