What is a PST file?

Outlook's PST file is a data file in which your emails, attachments, contacts, calendars and tasks, etc. are stored. This is the easiest way to keep a backup of your mailbox.

Manual Method: Outlook PST Password Recovery Without Third-Party Tool

Although Microsoft has not provided a direct option to remove PST file password, some old Microsoft PST Password Recovery Tools (like pst19upg.exe) and some workarounds available with Outlook can be used.

Manual Steps:

First, create a backup of your PST file.

Run Microsoft's old pst19upg.exe tool.

This tool can remove password protection or set a new password.

After this, you can import the PST file into Outlook.

Note: This method is quite old and does not work in new Outlook versions (Outlook 2016, 2019, 2021, and Microsoft 365).
