Microsoft Launches Preview of Exchange Admin API

Microsoft launched the preview of the Exchange Admin API on November 17. The new API is intended to close known feature gaps that exist in the Graph APIs and allow developers to migrate from EWS before Microsoft retires EWS in October 2026. Think of the Exchange Admin API as a discardable time-limited API that allows clients to submit cmdlets for processing. It’s certainly one way to approach the EWS problem!
