About this tag
Protocol deactivation refers to the disabling of legacy protocols to enhance security in Microsoft 365 services. As part of Microsoft's Secure Future Initiative (SFI), several outdated protocols, including the Relying Party Suite (RPS) protocol, will be blocked by default starting mid-July 2025.
