If you have password protected a Outlook data file (.pst), when you try to import or open the .pst file in Outlook, a dialog box similar to the following appears.

Without the password, you cannot open the .pst file, and you cannot access any of mail messages it contains. Microsoft is not able to help you retrieve lost file passwords. If you’ve forgotten or misplaced the password to a Microsoft Outlook data file (.pst), you can recover it easily with the Outlook Password Recovery program.

Outlook Data File Location

Before getting started, you need to know where your Outlook data file is saved.

1. Open the Mail applet from the Control Panel.

   

2. Click on Data Files button. This will open the Account Settings window.

   

3. Click the Data Files tab to see your Outlook data files, including PST and OST files. If you have multiple accounts in Outlook, you may notice several data files listed. In my example, I want to recover the password for the Test.pst file.

   

4. Select your password protected PST file, and click Open Folder button to open the folder containing the PST in Windows Explorer.

Recover Outlook Data File Password
