I was in my Outlook for Mac today and had pulled up .. Preferences then Account.  At the bottom of the screen I saw a + and -.  I was on my GMAIL account and hit the - button.  The window popped up that said "All items in this account will be removed from your computer. If you have copies of messages or other items on the mail server, the copies will not be affected.".  Well the DELETE button is flashing and it was also the exact same time my 3-yr old son grabbed by laptop from the floor and mashed the return key!  My wireless mouse was not quick enough to stop it... I stared in agony at the screen.  Is that entire account, and the saved email folders that was in it now gone forever?  Is there any way to find the .PST files like on a windows machine?  I have not re-booted or closed Outlook... I am still waiting in horror for your answers.  THANKS!
