How long does an apple pie last outside the refrigerator?

Generally an apple pie should be safe to eat for a good four to five days if prepared and stored properly in the refrigerator. However the moisture level of the filling will determine the quality of the pie during this time. For example, a more tart-like pie prepared with only thinly sliced apples and a caramel glaze will likely last a week with minor compromise to the texture of the pastry crust. The pie crust in a juicy deep-dish apple pie filling, however, will become soggy quickly as the moisture from the filling is absorbed by the pastry. It's quite possible that this pie will be very unappetizing in only two or three days even if it is still safe to eat.
