An Outlook data file password protects the PST file and stops anyone else from opening your emails, contacts, calendars, and other mailbox items. However, there are many situations where users can’t remember Outlook data file password, for reasons like an old archive file that is rarely opened, a password set by a former colleague, or a password that was changed and never written down. Since Outlook has no option to reset or recover it, users who can’t remember the password for an Outlook PST file often feel locked out of their own data. Through this write-up, we will discuss the common situations behind an Outlook data file password forgotten problem, after that we have shared free manual methods and an automated solution to access your PST file securely.

Also, it does not offer any option to recover or reset the password, due to which your emails, contacts, and calendars stay locked inside the file until the password is removed.

  • Outlook will keep asking for password every time you open the file, and it won’t load without the correct one.
  • Adding the PST file into a new Outlook profile or another computer won’t bypass the password prompt, so moving the file doesn’t solve the problem.
  • Outlook’s built-in Change Password option only works if you already know the current password, not when Outlook data file password is forgotten.
