I was trying to upgrade to Catalina and found I was out of space on my MacBook Air. I don’t have a lot of disk space on it, and I found that the mail space used by Outlook was >50GB! That’s pretty much half the disk.
I did some research and the Mail app has the same “feature” - download all emails.
Is there a mail app where I can only sync the most recent x days of emails, with older emails being removed from the device as time progresses?
