Apple Mail won't open
I clicked to send a "Report the User" email response to (3 daily attempts in a row, by) a hacker trying to access my Facebook account from their iPhone, and it forced APPLE MAIL v10.3 close immediately on my 2010 Mac Pro using Sierra 10.12.6. It now repeatedly Opens & CLOSES immediately, though I can receive messages via my Gmail account through the browser.
Should I delete that 1 empty "Report" email from 'Drafts'? Do I need to delete the Mail icon from my Dock and re-open the Application from its original Folder? If I do, will I lose all my boxes, messages & need to reload them somehow? I don't know how to re-legitimize my Apple Mail data, and hate relying solely on Gmail... HELP!
