Summary: In this article, we have provided stepwise instructions for removing PST password in Outlook. We have also provided methods to remove Outlook data file passwords (.PST), if you have forgotten the passwords.

Outlook allows you to add a password to Personal Storage Table (.PST) file so that only those who have the password can access the file’s contents. When you password-protect an Outlook Data File (.PST), a dialog box opens each time Outlook is launched.

If you do not want Outlook to prompt you for .PST file password every time you launch the application, you can remove the PST password.

To remove PST password, follow these steps:

  • Launch Outlook and go to File > Account Settings > Account Settings.
  • In the Account Settings window, select the PST file whose password you want to remove. Then click Settings.

Removing PST Password with pst19upg.exe

Microsoft offers a utility called pst19upg.exe that upgrades the .pst files to new standards. Apart from upgrading Outlook data files, this utility also removes the password of the PST files.

Note: You can use pst19upg.exe only if you fulfill the following conditions:

• You are using Outlook 2002 or earlier version

• The PST file is created in ANSI format and not in Unicode format

To use pst19upg.exe for removing Outlook PST password, follow these steps:

  • Close Outlook and create a copy of PST file (we are calling it PstCopy).
  • Run ScanPST.exe (located in Outlook directory) and repair PstCopy. Once done, move the file to the location of pst19upg.exe.
  • Press Windows + R. In the Run window, enter CMD and press ENTER.
  • Enter the path of pst19upg.exe and press ENTER.
  • Enter “pst19upg.exe -x PstCopy.pst” and press ENTER. A new file PstCopy.psx will be created.
  • Rename original PST file to something else. Then enter “pst19upg.exe -i PstCopy.psx” in the CMD and press ENTER. The utility will create a new PST that won’t have any password.

The pst19upg.exe tool is useful in removing PST passwords in old Outlook versions. However, the majority of Outlook users use Outlook 2007 or newer versions. For PST password recovery in these Outlook versions, you need to use an advanced PST password remover tool.
