Represents custom settings for a mail app that are stored in the user's mailbox as name/value pairs.
Last modified: November 24, 2014
The settings created by using the methods of the RoamingSettings object are saved per app and per user. That is, they are available only to the app that created them, and only from the user's mail box in which they are saved.
The name of a setting is a string, while the value can be a string, number, boolean, null, object, or array.
The RoamingSettings object is automatically loaded as part of the Context object, and is available by calling the roamingSettings property of that object when the app is activated. The developer is responsible for calling the saveAsync method after adding or deleting settings to save the settings in the user's mailbox.
The settings saved by using methods of the RoamingSettings object from a user's instance of a mail app are saved in the user's mailbox and are available only to that user's instance of the app. Mail apps also support the CustomProperties object, which lets you create a property bag stored with the current item.
