Dear invaluable Mozilla Community, I am about to download all my Hotmail/Outlook content (over 20 years worth!) to local storage as a .PST file. Can Mozilla help me acces, search and read those mails and attachments?

I have many years worth of e-mails in several folder in Hotmail/Outlook. I am about to download them to local HD storage. I will probably use the Outlook Export function which I understand will send me a massive single .PST file. Does Mozilla have a way by which I will be able to search, read and generally access those e-mails and their attachments? Thank you very much for your help - this is part of my campaign to become less dependent on the Big Tech Bros...
