Archive email to iCloud but without keeping a local copy
I have an archive of more than 60,000 emails in iCloud. I would like to be able to search this online and add to it without keeping a copy of each email on the drive of my MacBook Air. That is, my partner and I want to be able to access the iCloud email archive online from three different family computers without keeping copies of all those emails in the Mail program on each computer. Is this possible?
MacBook Air (2020 or later)
