Microsoft is implementing default blocks on legacy protocols and third-party applications for Microsoft 365 to enhance security. This includes deactivating the RPS protocol for SharePoint and OneDrive, as well as blocking the FPRPC protocol. Administrators will now need to give explicit approval for third-party applications to access files and pages, limiting user consent. These changes will begin in mid-July 2025 and are expected to be completed by August. Additionally, new security settings for Windows 365 will disable clipboard, storage, USB device, and printer linking by default on newly set up cloud PCs, with VBS, Credential Guard, and HVCI activated by default for those using a Windows 11 Gallery image. These updates for Windows 365 are planned for the latter half of 2025.
