My husband was drafting a Mail. There are lots of the early versions of it saved in the drafts box. However, he had almost finished it, was reviewing it and hit 'cancel' as he did not want to 'send'. Now the most up to date version of is nowhere to be found. I tried various searches, checked I was searching the correct boxes, checked drafts, trash on mail and on the system. Can he really have irretrievably deleted it in one click?
