Best Methods to Remove Password from Outlook PST

The methods to remove a password from a PST file depend on whether you know the current password or not. If you know the current password for the PST file, then you can use Microsoft Outlook to remove it. But if you don’t have the password, Outlook can’t remove it, and you will have to use a professional tool. Below, we will see the detailed steps to use both methods.

Method 1: Remove Known Password from PST File Using Microsoft Outlook

If you know the existing PST password, then you can remove it directly through Microsoft Outlook by following these steps:

Open Outlook and click on the File tab in the top-left corner.
Click Account Settings and select Account Settings from the drop-down menu.
Go to the Data Files tab. Select the PST file and click Settings.
In the Outlook data file window, click Change Password. Enter your current password in the old password box.
Leave the ‘New password‘ and ‘Verify password‘ boxes completely blank.
Click OK to save the changes.
