Can a mail app be localized on the primary language, like "de" and not explicitly for all sub regions like "de-de", "de-at"?
In the mail app manifest version 1.1 I use OfficeApp\FormSettings\Form\DesktopSettings\SourceLocation to specify the apps URL and add an <Override Locale="de-de" Value="apps URL for de-de"/> and have to do that for de-at, de-ch and so on as well.
Can this be simplified to override for Locale="de" or "de-*"?
