"Missing Gmail Labels/folders in MacBook mail: I had to re-image my entire computer. Everything was saved to iCloud. When I started apple mail again, I got all my emails to come back, but the folders they were filed in are gone. I don't really want to sort and file 86,000 emails back in to folders. Why did the folders disappear and can they come back?"
