Escalation path
- Open a Severity A case via the Microsoft 365 Admin Center.
- For BEC or account takeover, use the Microsoft Defender → Submissions portal.
- Pull Unified Audit Log entries before the 90/180-day retention rolls off.
Contract clauses to pull up
- A3/A5 EDU includes the K-12 student privacy DPA. Confirm whether your tenant has Defender for Office 365 enabled — many districts do not.
