Microsoft is retiring Exchange Web Services (EWS) in Exchange Online, with a phased shutdown beginning October 1, 2026, and complete retirement by April 1, 2027. You must migrate your applications to the Microsoft Graph API before the final deadline to maintain access to Exchange Online mailboxes. This retirement only affects Exchange Online in Microsoft 365 environments and does not impact on-premises Exchange Server installations. Organizations using EWS-dependent applications face service interruptions unless they transition to supported alternatives. The nearly 20-year-old protocol no longer meets modern security, scale, and reliability requirements.
