Summary
Microsoft is retiring Remote Event Receivers (RERs) in SharePoint Online as of July 1, 2027. RERs were part of the SharePoint Add-in model and relied on Azure Access Control Services (ACS) for authentication, which has already been retired. After the deadline, no remote event receiver will fire events regardless of registration method. Microsoft advises developers and organizations still using RERs to migrate to SharePoint webhooks before the cutoff date.
