Password-Protected PST Files via C#

In today’s digital environment, securing your data is more important than ever. Ensuring that your email data is protected with a password is a key step in maintaining security. For developers working with Microsoft Outlook data, managing password-protected PST (Personal Storage Table) files can be a critical task. This article will walk you through managing PST files with password protection using practical examples in C#.

Open a PST File with .NET API

Accessing files is a fundamental step in managing your email data. To load a file into your application, we’re going to use the PersonalStorage.FromFile method:

This code snippet opens the file located at the specified path (pstFilePath).

Check if PST File is Password Protected

Before attempting any operations related to passwords, it’s important to determine whether the file is protected by a password. You can easily check this using the IsPasswordProtected property:

This code checks if the file for password protection and outputs the result to the console.

Validate a Password

If you need to validate a password, you can use the IsPasswordValid method. Before that, ensure the PST file is indeed password-protected:

This code snippet first checks the file for password protection. If so, the code validates the provided password and prints out whether it is valid or not.

Add Password Protection to a PST File

If the PST file is unprotected, you can add a new password using the ChangePassword method:

Change Password

If the file is already protected, you can change the existing password with the same ChangePassword method:

This code checks the current state of password protection and changes the password.

Remove Password from PST File

If you wish to remove the password from a PST file, you can do so by setting it to null:
