You are very unlikely to be able to open the protected PST without the right login credentials.

You might be using different PSTs for each project, client or year. Constantly opening a new archive means needing to put in a password to access each one.

If you remember your existing password you can remove password protection to make these files easier to access.

  PC and installing Outlook, you will also copy various PST files.

How to Remove Password Outlook PST: 3 Possible Ways

Prior to beginning, find your initial PST file and also make a duplicate of it. Save your original PST file away until you are able to completely access your mailbox data

Choose the method that matches your situation.

Method 1: Remove PST Password Through Microsoft Outlook

You need to download a third party tool if you already know the password. All you need is you are familiar with the password then you need not download any other application.

This is generally the most straightforward approach.

Follow these instructions:

How to Remove Outlook PST Password



1. Open Microsoft Outlook on your Windows PC.

2. Select the File menu in the top left corner.

3. Choose Account Settings, and then select Account Settings again.

4. Expand the Data Files tab to see the Outlook data files that are connected.

5. Choose the password protected PST file you wish to change.

6. Click the Settings button.

7. Locate and press Change Password if available.

8. Insert the user's password to which you currently want to protect the PST file.

9. Do not provide a new password or verify password.

10. Click OK to apply the changes.

When you've finished adjusting the settings, close the dialog box and try opening the PST file again.

If Outlook stopped prompting for password, the modification has been implemented successfully.

This method can only be used if you know the existing PST password. The options for this method may also depend on your specific version of Outlook and the type of data file you are using.


Method 2: Use a PST Password Recovery Tool

What if you have forgotten your password and you cannot change it in Outlook?

However, this may be when a specialized PST password recovery program would be advantageous.

Unlike Outlook's own pre-installed settings, external recovery tools are able to operate directly with the PST file if it is secured by a password. But some have more advanced features and recover more data than others.


Here is the general process:

1. Look for a trusted Outlook PST password recovery software.

2. Visit the software developer's official website.

3. Download the Windows installation package.

4. Install the application and launch it.

5. Browse and locate the secure PST file to find on your computer.

6. Attempt the recovery guide from the app.

7. Review the results and recovery options.

8. When you've recovered the password, open the PST in Outlook and remove the password from the file.

Before installing any other third-party utility, determine that the utility is compatible with the version of your PST and Outlook. Then consider the security policies of the utility and stay away from tools that make exaggerated recovery claims.

Another thing: your Outlook archive might have business-sensitive, customer-sensitive or even personal files or emails attached to them. Please don't upload those into some unknown online service to get a password.

Method 3: Open an Earlier Outlook PST Backup

You might not need to waste time restoring an old password. Perhaps you have another duplicate of this Outlook archive saved elsewhere on your computer or on an external drive.

If that backup is available, then it can be used to recover the necessary emails.

This technique is handy, especially if you have taken multiple backup copies of your Outlook data earlier.

Follow these steps:

1. Look for Older Pst Files on Your Computer, External Drive, or Backup Folder.

2. List another backup that might include the needed mailbox data.

3. Open with another copy.
