Microsoft to shut down Exchange Online EWS in April 2027
Microsoft has announced that the final shutdown for EWS (Exchange Web Services) will be on 1 April 2027, but note that EWS will continue to function in on-premise installations. Microsoft actually first warned of the demise of EWS in 2018, so this should not be a huge surprise, but more of a reminder.
Please contact your First Technology account manager to connect you with our Exchange specialists to assist with understanding if you are impacted by this, and what the best way to move away from being dependant on EWS
