Preservation Lock is only available for static retention policies and not supported for adaptive scopes.

From Microsoft docs:

“Preservation Lock can only be applied to retention policies configured with static scopes. Adaptive scopes do not currently support Preservation Lock.”

Step 2 – Analyzing the Case Data

RPolicy2 → Adaptive scope (Scope2: SharePoint Online sites). ❌ Not eligible for Preservation Lock.

RPolicy3 → Static scope (Microsoft 365 groups). ✅ Eligible for Preservation Lock.

Step 3 – Conclusion

Only RPolicy3 qualifies for Preservation Lock.
