MC270671 – Microsoft is making some changes to the Hybrid federated search. As part of search modernization in Microsoft 365 Microsoft is updating the infrastructure used by SharePoint Server’s Hybrid federated search. As part of the process, customers who are using the Hybrid federated search with hybrid SharePoint deployments will need to update their configuration to continue using hybrid search with SharePoint Server and SharePoint Online.
