Need helping putting both my iCloud emails onto my windows laptop

Hi everyone,

I recently got a windows surface for Christmas for university and have managed to have my main iCloud email in the iCloud mail. I only recently found out that all my university emails go towards a different iCloud email I use. I’m wondering if there is anyway to have both emails on the iCloud mail on my laptop. I have both on my mail on my iPhone if that helps

Thanks in advance
