What it is
Microsoft Purview: Information Protection - Rights Management connector – Certificate-based authentication is a Microsoft 365 roadmap item published via Microsoft Release Communications. Current status: In development.
What it does
The Microsoft Rights Management (RMS) connector is moving from shared-secret authentication to certificate-based authentication, improving its security posture. With this update, administrators configure their own Microsoft Entra app registration and certificate, then use the new PowerShell module to configure the certificate for each workload (Connector, Exchange, SharePoint, and FCI). New PowerShell cmdlets handle certificate import, registry configuration, private-key permissions, and validation. As part of this change, the connector setup no longer provisions an Entra service principal or issues a shared secret on the customer's behalf. Customers should plan to register an Entra ID application and upload a certificate before installing or upgrading the connector.
Why you should care
Board
Security/compliance control — fund Steady before more seats.
CISO
Prioritise as Steady control; wire into IR and GRC evidence paths.
CFO
Map licence or consumption impact to the frozen value case; avoid seat spray.
Adoption
Pilot with a named cohort and measure changed work, not vanity clicks.
Suggested action
Wave 0 first: Security → GRC → Cost & Value → Licence → Adoption. Add to Horizon watchlist with an owner. Pilot only after Steady controls for the affected surface are in place.

Communication needed
- Security: Lead review; confirm control mapping before enablement.
- GRC: Update AI/agent register and evidence path; confirm DPIA triggers if personal data is in scope.
- FinOps: Forecast seat or credit impact; align to frozen value case.
- Adoption: Plan cohort messaging, clinics, and success measures.
- Comms: One story for board and staff — what changes, what does not, who owns risk.
Benefits
- May improve productivity on a specific Microsoft 365 surface when permissions and data quality allow.
- Roadmap visibility helps Horizon planning without guessing dates.
Risks
- Status and dates change; treat MRC as directional, not a contract.
- Enabling without Steady controls can amplify overshare or cost leakage.
- Preview or rolling features can change behaviour; fence exploration on Pane 12 Frontier.
