Seriously, he tried to delete them and committed the deed. That’s the good news. Guilty behavior. Reckless disregard, and what have you. Lock him up.
Well I don't know about "really delete" but I delete my Gmail emails all the time.
It's deleted but not really deleted. Pick a common word or term to search on in your Gmail Inbox that has been used alot in your emails, something like "Trump" or "baseball". Emails you received five years ago and deleted will show up again based upon the search item.
