My outside outlets suddenly all went dead. I turned the breaker switches of and then on. Stlill the outlets are dead. What I can do to get them working again. All the inside outlets are working.

If there is no GFCI breaker in the panel that controls those outlets, I would check all the outdoor outlets to find the GFCI outside that is tripped. Or else, go check all the GFCIs inside the house. I have seen situations where the GFCI in a seldom used powder room (in a garage another time) controlled the outdoor outlets, and when it tripped, I got the call because no one could find the problem.
