Microsoft's retirement of Exchange Web Services (EWS)

Microsoft has announced that Exchange Web Services (EWS) in Exchange Online will be retired on October 1, 2026. To mitigate this change, we plan to transition functionality that currently relies on EWS to the Microsoft Graph API, which is Microsoft’s recommended and supported approach going forward.

Our team is actively working on a plan to ensure a smooth transition and maintain continuity of the affected functionality. At this stage, you don't need to take any immediate action.

We will share more information as our planning progresses, including any relevant information about impact, timing, and next steps.
