“Barracuda Cloud-to-Cloud Backup is migrating from Exchange Web Services (EWS) to the Microsoft Graph API in stages”
Exchange Web Services (EWS) Deprecation and Barracuda Cloud-to-Cloud Backup (Barracuda Campus) (2026-08-31), read 2026-10-21.
What to do. Barracuda moves backups from EWS to Graph in stages. Reauthorize the connection now to grant the Graph permissions. Graph does not cover recoverable items, archive or group mailboxes yet. Frontline and Kiosk mailboxes need EWSEnabled set to True at tenant level.
