The Final Countdown to Remove EWS from Exchange Online Begins

Microsoft announced the dates leading to the final retirement of Exchange Web Services from Exchange Online. If all goes well, the EWS retirement in the cloud will happen by May 2027. Challenges still exist. Microsoft must remove EWS from its own apps, including Outlook, and help tenants and ISVs make the leap to Graph APIs. Plans are in place and progress is being made, but will everyone be ready when Microsoft starts to remove EWS permanently from Exchange Online in April 2027?
