Can I hack a protected PST file?

Set a password to protect Outlook data

A password can be set on an Outlook data file (.pst) to prevent unintentional intrusion attempts by others who share your computer. If you use a password, you will be prompted for the password when you start Outlook and when you open the file for the first time in an Outlook session.

Security advice: Outlook data file (PST) passwords are not intended to provide security from willful malicious attempts to access your information. A better way to restrict access to your data is to use a password-protected Windows user account for each user of the computer. For more information, see Help and Support in Windows.
