RequestedLocales

Set the list of requested locales for the application in order of preference. It will cause the corresponding language pack to become active.

Values

RequestedLocales accepts either an array of locale codes or a comma-separated string, in order of preference:

• ["de", "en-US"] as an array.
• "de,en-US" as a string.

The first locale with an available language pack becomes active. The policy is applied when its value changes, so a user who switches language afterwards is not switched back.

Examples

policies.json

{
  "policies": {
    "RequestedLocales": [
      "de",
      "en-US"
    ]
  }
}
