“Our system will be fully migrated to the Graph API before the EWS API is switched off”
1636 - Issues resulting from Microsoft's deprecation of EWS (Redstor Help Center), read 2026-10-21.
What to do. Redstor's Exchange backup uses both EWS and Graph and will be fully on Graph before EWS is switched off. A Microsoft 365 global admin must update the permissions of every existing Exchange backup set in the RedApp (one consent per tenant, four read-only permissions). If backups finish with errors, check that EWSEnabled is True at both the organisation and user level.
