How to Recover Password for an Encrypted Outlook PST File

Microsoft Outlook users who want to add an extra layer of protection for their data should password protect their PST files. This will ensure that only authorized users will be able to access the information in a PST file. But what if you forget the password for your PST file?

Because there can be a lot of sensitive information contained in PST files, customer’s contact information or contract drafts are just two examples that come to mind, some businesses like to encrypt their Outlook PST files.

When you encrypt a PST file, you ensure that unauthorized parties cannot get at the data within because only people who have a password to open the file can do so.

How to password protect a PST file

  • Open your Outlook program. Go to the “File” tab
  • Go to “Account Settings”
  • Go to “Data Files”
  • Select the PST file that you want to set a pass word for. Click “Settings”
  • Choose option “Change password”. A dialog box will open.
  • Leave “Old password” blank.
  • Type in your password in the “New password” box.
  • Type it in again in “Verify password” box
  • Click “Ok”

So this is how you set a password for your PST file. If the PST file is already password protected but you want to set a new password, go through the same process BUT, type in your old password in the “Old password” box.

What if, however, you have forgotten the password of your PST file?
