Unable to Open Password-Protected PST File: How Do I Fix This?

I am facing an issue with my Outlook PST file. The file is password-protected, and suddenly, Outlook has stopped accepting the correct password. Whenever I try to open the PST file, it shows an error saying the file cannot be opened or the password is incorrect. I am 100% sure that the password I am entering is right, but still, Outlook is not unlocking the file. I urgently need to access some important emails stored inside this PST. Can anyone guide me on why this issue occurs and how I can fix or open a password-protected PST file? Also, please suggest any safe method or tool to remove or recover the PST password without damaging the data.
