Microsoft Purview | Information Protection: Sensitivity labels to discover private teams and protect shared channels

Microsoft Purview now offers two new controls under the Information Protection feature, designed to improve the controls around private team discoverability and provide additional controls for shared channels in Teams channels. The controls are accessible via the sensitivity label creation/edit process in the Microsoft Purview Compliance portal.

The new version of the create/edit flow introduces a new section called Private team discoverability and shared channel settings, which has two subsections for control over private teams and shared channels. The Private teams discoverability control allows private teams to be searchable in the Teams app if the label is applied to it, enabling admins to create/edit labels that allow private teams' discoverability. In contrast, Shared channel controls provide access controls to shared channels in a tenant based on applied labels, allowing for the restriction of sharing with internal teams only or teams that have the same label applied.

Note that for the label-based control to take effect, the admin must turn on Private team discoverability from the Teams Admin Center for scoped users or all users in the tenant through Teams policies. These changes are associated with Microsoft 365 Roadmap IDs 165698 and 174575. Public Preview is expected to be rolled out between early and mid-February, while the Standard Release is expected to be completed by early March.
