Answer: I think the problem is directly related to the change of location. Indoors the temperature is usually warm and dry and the intensity of light is much lower than outdoors. Your plant is trying to adjust to these changes and in the process is dropping fruit. There's not much you can do to remedy the situation - outdoors is too cold at this time of year so don't take it back out. Help it make the adjustment by providing your tree with bright light and adequate water. Try misting the leaves to increase humidity around the plant. Eventually it will adjust and produce new leaves and flowers. Once it has recovered it might even produce fruit!
