If I exported those without “Export all subfolders” on, then I’d be saving “Work TO DO,” “TO KEEP,” and “Electronic Receipts,” but not the folders underneath them. For example, here is a section of some of my saved mailboxes: If you forget to do this and then delete the originals from Mail…well, you’ll be sad.

See that “Options” button I’ve called out? Underneath that is the very important checkbox that you’ve gotta toggle on if the mailbox you’re exporting has subfolders. Whichever way you do it, though, Mail will next want to know where you intend to store your mbox file. As it turns out, Apple has now hidden the “Export all subfolders” checkbox under a button, and if you aren’t paying attention, you could end up deleting critical info! Here’s how it works now: As I mentioned in the previous tip, you’ll click on your mailbox from the sidebar, and then you can right-click on it to choose “Export Mailbox” from the contextual menu or pick that option from the menus at the top (shown in my screenshot above). However, there’s one piece of it that needs an update. That still works (as long as you’re aware of the caveat at the end of this article), so if you’re looking to clean up your Mail program, go check it out.
