How to Successfully Remove a Password from a PST File Without Data Loss?

Source: Dev.to

Issue Overview

I am facing an issue with an old Microsoft Outlook PST file that is protected with a password. I no longer remember the password, and as a result I cannot access the important emails, contacts, and calendar data stored in that PST file.

Constraints

• The PST file contains critical business emails, so creating a new Outlook profile is not an option.
• I am concerned about potential data loss or file corruption during any password‑removal process.

Attempts Made

• Tried basic methods such as changing Outlook settings.
• Searched for manual tricks online, but none of them worked properly.

Request

Can anyone suggest a reliable and safe method to successfully remove the password from a PST file?
