STEP 1: On the File menu, click Data File Management to open the Account Settings dialog box.
STEP 2: On the Data Files tab, click the Personal Folders file (.pst) for which you want to create a password, and then click Settings to open the Personal Folders dialog box.
STEP 3: Click the Change password button.
• This button does not appear if your e-mail account runs on Microsoft Exchange. Your Outlook folders are already protected by your Exchange password.
STEP 4: In the New password box, type your new password. The password can be up to 15 characters long and case-sensitive.
• Use strong passwords that combine uppercase and lowercase letters, numbers, and symbols. Weak passwords don’t mix these elements. Strong password: Y6dh!et5. Weak password: House27. Passwords should be 8 or more characters in length. A pass phrase that uses 14 or more characters is better. For more information, see Help protect your personal information with strong passwords.
• It is critical that you remember your password. If you forget your password, Microsoft cannot retrieve it. Store the passwords that you write down in a secure place away from the information that they help protect.
STEP 5: In the Verify password box, type your new password again.
STEP 6: If you share a computer with others, don’t select the Save this password in your password list check box. Anyone with access to the computer could potentially open your .pst file. If your Windows user account is password protected, and no other user has access to the computer, you can select the Save this password in your password list check box if you want to avoid entering your password each time you need to use the .pst file.
FINAL STEP: Click OK twice, and then click Close.
