How to Break Outlook PST Password Without Data Loss?

I have an old Microsoft Outlook PST file that contains important emails, contacts, and calendar items. Unfortunately, I forgot the password, and now I can not open the file in Outlook. This PST file belongs to me, and I only want to regain access to my own data. I am worried that trying random tools or manual tricks might corrupt the file or cause permanent data loss. In this situation, what is the safest and most reliable way to recover or remove the PST password without damaging the file or losing any mailbox data?

Professional PST tools do not brute-force the password.
They bypass the password header
open the PST in read-only mode
let you export emails to a new PST (no password)

Well-known tools
PST Recovery / PST Viewer software

did you try anything before realizing you forgot the password, like writing it down somewhere or using a password manager?
