How to download all the mails from Mail to my computer?

Hello, I would like to make a backup of all the emails I received and sent using my work account to my computer. I used Mail few days ago. Could you please let me know how to do it? Thanks.

Just to get some clarification. You would like to backup your emails at work and then put them on your computer at home if I understand you correctly. It would help if you could tell us what email programs you are using on each computer.

My computer at home is the laptop provided by school. I used to use Outlook but for some reason, it gave me error messages all the time and then suddenly never launched again. I then used Mail.

I want to backup the emails at work.
