Hi. I've had this annoying issue for 3 months now. I absentmindedly tried to send a friend with a huge attachment. IDK what I was thinking cuz it was surely too big to send. It's been stuck in my 'Drafts' folder all this time. I cannot delete it or move it. I cannot find it in Finder to manually 'try' to delete it. Would anyone know how I can find/nuke this file? When I delete it in Mail, it just turns grey temporarily. I've been looking at this for 3 months now and it needs to go.
