The PST (Personal Storage Table) file in Microsoft Outlook stores emails, contacts, calendars, and other Outlook data. If you have put a password on a PST file but have now forgotten the password, opening it in Outlook 2021 can be a bit difficult. However, some ways that can help you access the PST file without the password.

If you have forgotten the password of your Outlook PST file and are unable to access important emails or data, I would recommend that you try the GainTools PST Password Recovery Tool. I used this tool myself and recovered my old password within a few minutes, without any data loss.
