“The Graph backend replaces the legacy EWS-based backend and has been feature-complete since ADITO version 2026.0.”
Calendar Backend Migration (EWS to ExchangeGraph) | ADITO Platform, read 2026-10-25.
What to do. ADITO 2026.0 includes all features of the Graph calendar backend. Replace the alias of type MS-Exchange (Webservice), the EWS backend, with a new alias of type MS-Exchange (Graph) and make it the active calendar backend. Add an AuthenticationProvider alias for permission sync, import the Graph modules and update the autostart process. Free/busy queries on Graph no longer return UIDs, so adjust customizing that reads them.
