How to remove PST password manually?

Now, let's delve into how we can manually remove a password from a PST file. If you're someone who enjoys hands-on processes and learning new tricks, you'll find these steps particularly interesting.

However, there's one thing to keep in mind before we get started. To employ these manual methods, you need to have Microsoft Outlook installed on your computer. So, if you're all set with that requirement, let's venture into the manual methods of PST password removal.

Method 1: Remove PST password using pst19upg.exe

The pst19upg.exe utility is a tool provided by Microsoft that was primarily used for upgrading the format of PST files in older versions of Outlook. A lesser-known feature of this utility is its ability to remove passwords from PST files. Here's how you can use it:

  1. Close MS Outlook
  2. Make a copy of the PST file
  3. Run SCANPST.exe and repair the PST copy
  4. After that, move the file to the pst19upg.exe location
  5. Open the command prompt
  6. Enter the location of the pst19upg.exe and hit Enter key
  7. Enter pst19upg.exe -x PSTFileCopy.pst and hit Enter key
  8. After that, it will create a new file PSTFileCopy.psx
  9. Rename the original PST file different name
  10. Enter pst19upg.exe -i PSTFileCopy.psx and hit Enter key
  11. After that, it will create a new file without any password.

Remember, this method is only applicable for older versions of Outlook (2002 and earlier). The pst19upg.exe utility may not be available or functional for newer versions of Outlook. Always ensure that you have backups of your PST files before attempting this procedure, as it involves significant modifications to the file structure.

Method 2: Remove password from PST using the Change password option

This method is suitable for users who know their current PST file password and want to remove it. The process involves using Microsoft Outlook's built-in options to change or remove the password from PST file. Here's a step-by-step guide:

  1. Launch MS Outlook and go to the File tab
  2. Click Account Settings and choose the Account Settings option
  3. Click the Data Files tab and select the PST file
  4. After selecting PST, click the Settings option
  5. Click the Change Password button and enter your old password
  6. Leave the remaining fields blank and click the OK button.

This process will effectively remove the password from your PST file. From this point forward, you won't need to enter a password to access the contents of this PST file. It's a straightforward and safe method, as it doesn't involve any external tools.

Remember, if you've forgotten your PST password, Outlook cannot retrieve it. In this scenario, you need a third-party PST password recovery tool, which brings us to the next part of this guide.
