Collaboration Protection – 2026-09-15 Update
Released
Exchange scanning moves to Microsoft Graph API
Collaboration Protection has transitioned Exchange Online scanning from Exchange Web Services (EWS) to Microsoft Graph API, aligning with Microsoft’s platform modernization following EWS’s retirement. Email protection, the primary security workload, continues uninterrupted with no change to detection capabilities. As a result of this change, scanning of calendar events, contacts, tasks, notes, and sticky notes is no longer supported.
Quarantine cleanup correction
We’ve corrected an issue where some expired quarantined items were not being cleaned up in line with the retention period defined in the policy.
Reminder
To ensure continued support for inbox rules scanning via Graph API, customers who haven’t already done so must grant the updated Microsoft Graph API permissions via the notification banner in the Collaboration Protection Portal.
