You have a Microsoft 365 subscription. You need to create a data loss prevention (DLP) policy that is configured to use the Set headers action. To which location can the policy be applied?

The 'Set headers' action in a DLP policy is specific to Exchange email, allowing custom headers to be added to messages that meet policy conditions, and it is not an available action for other locations like OneDrive, SharePoint, or Teams.

OneDrive accounts store files, and DLP actions for OneDrive relate to file access, sharing, or notifications, not setting email headers.

SharePoint sites store documents and web content; DLP actions for SharePoint relate to content access, sharing, or policy tips, not email headers.

Teams chat and channel messages are communication content, and DLP actions for Teams focus on message content, not setting headers on email messages.
