Computer data security is one of the most critical issues for most organizations and even for the individuals. These computer files contain very crucial information about an organization or an individual. But if it falls into the wrong hands, it becomes very dangerous and a frustrating situation for them. In such a critical situation, you must protect your computer files by applying passwords to them. Password protection provides security to your computer data and files against any unauthorized or misuse or theft.

In these days email has become the most popular medium for computer users to exchange or share crucial information from one side to another. MS Outlook is one of the popular email applications that helps users send and receive email messages. Other than sending and receiving email messages, it also supports multiple features like calendaring, contact management, task management, note taking, journal creation, and web browsing. All the mailbox items of MS Outlook are saved into an Outlook Data file, which is called PST or Personal Storage Table. Outlook mailbox is very crucial for Outlook users as it contains crucial emails and other mailbox items. Your PST file can be easily accessed by any unauthorized user if it is not protected or your Windows user account is not password protected. Therefore, you must password protect PST file by using password protection feature of Microsoft Outlook.

Step 1: First, open your Microsoft Outlook program.


Step 2: Now click the File tab in the taskbar. Click > Data File Management…


Step 3: The Account Settings dialog box will pop up. On Data Files tab, select the Outlook data file and click Settings.

  • In MS Outlook 2000:C:\Program Files\Common Files\System\MAPI<locale ID>NTscanpst.exe
  • And, in MS Outlook 97/98:C:\Program Files\Common Files\Windows Messaging\scanpst.exe

Note: Don’t use backup option in SCANPST.EXE as you working with a duplicate copy of PST file.
