AI in SharePoint (Knowledge Agent) – Important Update for EU and UK Tenants

AI in SharePoint, formerly Knowledge Agent, is refreshed using Anthropic models for advanced capabilities. EU and UK tenants must explicitly enable Anthropic as a sub processor in the Microsoft Admin Center by March 2026 to continue using the preview; otherwise, users will see an error. You’re receiving this message because your tenant is opted in to the SharePoint Knowledge Agent public preview, which is being refreshed and renamed AI in SharePoint. As part of this refresh, AI in SharePoint now uses an Anthropic reasoning model to support advanced, action-oriented capabilities such as planning and executing tasks across SharePoint sites, pages, lists, and libraries. Due to EU data boundary commitments, this change requires explicit admin action for tenants based in the EU and UK. When this will happen: Public Preview (Production): Rolling out starting March 2026 Who is affected: Microsoft 365 Copilot–licensed users in tenants who have opted-in to public preview and are based in the EU or UK.  How this affects your organization: If you previously opted into the Knowledge Agent (now AI in SharePoint) public preview but Anthropic is not enabled as a sub processor for Microsoft Online Services, users will not be able to use AI in SharePoint once the refreshed preview rolls out. This setting is disabled by default in the Microsoft Admin Center for EU and UK tenants. Background information: To support advanced reasoning and action-oriented capabilities in AI in SharePoint, the public preview refresh will use an Anthropic reasoning model, selected based on internal evaluations, testing, and capacity considerations. Because Anthropic models are currently excluded from EU data boundary commitments, Anthropic is automatically disabled as a sub processor for Microsoft Online Services in EU and UK tenants. To continue using the Knowledge Agent (now AI in SharePoint) public preview, tenant admins must explicitly enable Anthropic in the Microsoft Admin Center. What you need to do to prepare: If you would like your tenant to continue to experience the Knowledge Agent (now AI in SharePoint) public preview, you must enable Anthropic as a sub processor for Microsoft Online services for the tenant.
