The reported message is marked with the selected verdict, and an email message is automatically sent to notify the user who reported the message.
When automatic notifications use the default template, users receive notification emails in their preferred language based on their Outlook language settings.

Localized templates don't change message verdicts, classification logic, or automated investigation behavior.
