Legal: Files & other data assets; Research: Groups & sites
Microsoft Purview sensitivity labels support multiple scopes that determine which resources the labels can protect and which protection settings administrators can configure.
First selection: Files & other data assets.
The legal department requires document-level protection for Microsoft Word files stored in SharePoint and distributed to external counsel.
The Files & other data assets scope supports sensitivity labels that apply encryption and content markings directly to supported documents.
Because the protection is associated with the document itself, configured encryption and markings can remain with the file when it is downloaded or shared outside its original SharePoint location.
Second selection: Groups & sites.
The research department requires collaboration-level protection for a Microsoft Teams environment.
The Groups & sites scope supports sensitivity labels applied to Microsoft Teams, Microsoft 365 groups, and SharePoint sites. These labels can configure privacy settings, guest access restrictions, external sharing controls, and access restrictions for unmanaged devices.
The Emails scope is intended for email protection, while the Meetings scope controls supported meeting and chat protection capabilities.
Technical consideration: Groups & sites labels do not automatically encrypt every document stored within the associated container. Additionally, restrictions for unmanaged devices require the supporting Microsoft Entra Conditional Access configuration.
Therefore, Files & other data assets is appropriate for Legal, while Groups & sites is appropriate for Research.
