I recently found an old PST backup file from my previous Outlook account, but the problem is that it is password-protected. Unfortunately, I do not remember the password anymore. I tried opening it in Outlook, but it keeps asking for the password, and I have no clue what it could be. Is there any way to recover or remove the password from this PST file so that I can access my old emails and contacts? Any reliable solution or tool recommendation would be really helpful.
