Royal icing will keep at room temperature for 2 weeks. Freezing royal icing is not recommended. The best way to store it is in a grease-free, airtight container. If that is not available, cover the icing bowl with a damp kitchen towel (not paper); then cover with plastic wrap, securing the wrap with a rubber band. Before using the icing, stir thoroughly, or rewhip with an electric mixer.
