Hello, at school, people use the Windows version of Microsoft Outlook. They set some kind of automatic archive so that their mailbox don't get full. I have been using Mail which came with the Mac OS 10.8.5. Recently, I receive a message daily saying that my mailbox is going to be full. I don't want to delete emails (got lots of important ones with attachments). How can I solve this problem under Mac OS? Is there a similar archive feature in Mac?
