The Complete Guide to Outlook PST Password Recovery

If you use Microsoft Outlook and need to recover your PST file password, don’t worry–you’re not alone. Because you may go months or years without needing to look at Outlook PST files, lots of MS Outlook users need Outlook password recovery at some point in time.

In this comprehensive guide, we’ll walk you through the steps necessary to regain access to your data. We’ll also explain what to do if you forget your PST password. So, whether you’re a new user or an experienced one, read on for all the information you need.

What Is an Outlook PST File Password?

Password ProtectionAn Outlook PST file password is a security measure that can be used to protect the contents of a PST file from unauthorized access. The password is typically set by the file’s owner, and it must be entered in order to open the file.

Outlook data files usually contain important information such as email messages, contacts, calendar items, and tasks. Therefore, it’s important to choose a strong password that will be difficult for others to guess.

The password is required when you open the PST file in Microsoft Outlook. The password is also needed if you try to access the file from another computer. The password is not required if you open the file in another program, such as Microsoft Word or Microsoft Excel.

Password-protected PST files are beneficial because they offer an additional layer of security for sensitive data. By preventing unauthorized access to a PST file, you can help ensure that the contents of the file remain confidential.

In addition to preventing unauthorized access, an Outlook PST file password can also help to deter data theft by making it more difficult for thieves to copy or move the contents of the file.

While an Outlook PST file password is not a perfect security measure and has limited password protection, it can be a helpful tool for protecting sensitive data or use a tool to recover forgotten passwords. If you need to recover the password to your email accounts, read this article.

Where Is the Outlook PST Password Stored?

Outlook PST passwords are stored in the Windows Registry. The location of the registry key depends on the version of Outlook that you’re using.

For older versions of Outlook, the key is located at HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider.

For newer versions of Outlook, the key is located at HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\[Profile Name]\9375CFF0413111d3B88A00104B2A6676\[Account Index].

The passwords are encrypted and are not viewable without a tool that can decrypt them. The encryption used is based on the Windows user account that is currently logged in. If you change the password for the Windows user account, the Outlook PST password will also be changed.

The Outlook PST file password is not synchronized with the Exchange server and is therefore not viewable by the Exchange administrator. If you forget the password but want to view your PST files again, you will need to create a new PST file and re-import your data.

How to Recover the PST Password if You Know the Old Password?

If you know the old password and want to change it, follow these steps: 

  1. Start Microsoft Outlook.
  2. On the File menu, click Account Settings, and then click Account Settings.
