I managed to get out of the game play area in Elsweyr. Although I wouldn't recommend it, because after running across flat plane and falling off the edge I couldn't get back into the game, it finally said I had reached my message rate limit and kicked me out out of the game. Not even travelling to a Wayshrine would work. The Only thing what would reset things would be to delete the application saved data on the PS4. The game area can be breached at the end of Sleepy Senche Mine. When you are facing the open marquee, turn left up the wooden planks, then right, then turn right. Go up the short pointy rock face and jump onto the marquee (this may take a few attempts to get it right). Go across the marquee top and the jump onto the rock Face. On top off this you will be looking at the out bound play area. Going any further you may not get back into the game.
