I assume all my email is readily available to authorities, whether I deleted it or not. E-mail is inherently not designed to be private. I also assume multiple copies of it exist in various locations around the globe. There's a phrase: 'Dance like no one's watching, send e-mail like your email is going to be leaked'.

But I feel your pain. Outlook is the worst. When you delete items from Trash, it sends them into another folder where you can 'recover' deleted e-mails. Everyday Joe assumes the e-mails are deleted when you purge trash, but oh no, dark patterns striketh again!
