SharePoint and OneDrive agents using the .agent file format will be upgraded to integrate with Microsoft Copilot’s extensibility ecosystem. From mid-November 2026, new agents use the Copilot Agent Builder, with .agent files supported until March 2027, after which they stop working. Organizations should prepare to upgrade agents and adopt new management and governance tools.
