New agents become Microsoft 365 declarative agents. Existing .agent files keep working through March 2027; Microsoft plans to disable them from early April, and agents not upgraded will no longer be accessible. Upgraded agents must be re-added to Teams chats and channels. Agent Builder does not automatically grant access to source files. Eligible Copilot Chat users can access declarative agents, but agents using shared tenant data such as SharePoint may incur usage-based Copilot Credit charges. Copilot in SharePoint requires a Copilot licence.","sledRelevance":"Universities, districts and agencies that let staff build SharePoint agents now have a forced migration with a March 2027 deadline and a possible cost change for Copilot Chat-only users, who are the majority in many SLED tenants.","evidence":"Vendor-authored blog post summarising Microsoft's own schedule and licensing; no customer data. It cites a roadmap item (575298) still marked in development.","architectureImplications":"Agents move from files stored in SharePoint libraries to declarative agents managed in the Microsoft 365 agent platform. SharePoint stays the knowledge source, but placements in pages and Teams must be rebuilt.","governanceImplications":"Each legacy agent needs an owner, purpose and destination (Copilot in SharePoint, a skill, a declarative agent, or retirement). That forces an agent inventory many institutions do not have.","securityPrivacyImplications":"Agent access and content permissions are separate checks; permissions may need to change for the intended audience, which risks oversharing if done hastily.","caveats":"Vendor source; dates are Microsoft's and may slip. The post gives no GCC or GCC High timing, so US government tenants should confirm their own dates. Credit costs are not quantified.","streamIds":["microsoft"],"roles":{"sales":"Sales framing: this is a dated, forced change. SharePoint Agents created by staff must be inventoried, re-homed or retired by March 2027, and Copilot Chat-only users may start drawing on metered Copilot Credits. That gives a bounded reason to engage universities and agencies now on agent inventory and cost controls. Do not present it as a feature upgrade with guaranteed value; the post contains no customer outcomes. Ask how many agents exist, who owns them, and whether finance knows about possible credit charges.","engineering":"Engineering framing: legacy .agent files are being replaced by declarative agents in the Microsoft 365 agent platform. Engineers should inventory agents with SharePoint search, Purview audit and the PowerShell scripts the post links. Map each to a destination, re-check content permissions separately from agent access, and rebuild Teams and page placements. For Copilot Chat users, configure Copilot Credit billing and caps before upgrading SharePoint-grounded agents. Confirm GCC or GCC High timing, which the post does not give.","delivery":"Delivery framing: treat this as a lifecycle project with a March 2027 deadline. Steps: inventory agents, assign an accountable owner to each, choose a destination by business outcome, test representative prompts and citations, then re-communicate access points to users. Retire agents with no owner. Delivery teams should schedule work so page and Teams changes and permission fixes finish well before April 2027, and give finance a view of any credit-based charges."},"roleDetails":{"sales":{"customerProblem":"Institutions with staff-built SharePoint agents face a forced migration and possible new metered costs.","stakeholders":["Microsoft 365 / collaboration service owner","CIO and IT security","Finance or licensing manager","Departmental agent owners"],"discoveryQuestions":["How many SharePoint agents exist and who owns them?","Which agents are used by Copilot Chat-only users?","Is Copilot Credit billing configured and capped?","What is your GCC or GCC High timing for this change?"],"valueHypothesis":"An early agent inventory and migration plan may avoid broken agents after March 2027 and surprise credit charges.","potentialEngagement":"A fixed-scope agent inventory and migration-readiness review ahead of the mid-November change.","unsupportedClaims":["That the migration adds value for users","Any cost figure for Copilot Credits","That GCC tenants follow the same dates"]},"engineering":{"fit":"Relevant to any SLED tenant where staff created SharePoint agents.","architectureIntegration":"Move .agent files to Microsoft 365 declarative agents via Agent Builder, Copilot in SharePoint or skills; rebuild Teams and page placements.","prerequisites":["Agent inventory","Owner for each agent","Copilot Credit billing setup","Permission review of knowledge sources"],"constraints":["Dates are vendor-stated and may slip","No US government cloud timing given","Agent Chat web part still in development"],"security":"Re-check source permissions separately from agent sharing to avoid oversharing during upgrade.","proofOfValue":["Test representative prompts and citations before and after upgrade","Confirm Copilot Chat-only users' credit consumption in a pilot group"]},"delivery":{"work":"Inventory, re-home or retire SharePoint agents before the March 2027 deadline.","dependencies":["Microsoft rollout from mid-November","Billing configuration","Department owners' availability"],"ownership":"Microsoft 365 service owner, with department agent owners for each agent.","skillsAdoption":"Train agent builders on Agent Builder; give users updated access points.","governanceCheckpoints":["Inventory complete before rollout","Each agent has an owner and destination","Credit caps approved by finance"],"acceptanceCriteria":["Proposed: 100% of discovered agents assigned an owner or retired","Proposed: upgraded agents pass a prompt and citation test set","Proposed: no unbudgeted Copilot Credit charges in the first billing cycle"],"risks":["Agents break after April 2027","Oversharing from permission changes","Unexpected metered costs"]}},"retrievedAt":"2026-11-02T14:35:57Z","enrichedAt":"2026-11-02T14:41:07Z","enrichmentBasis":"retrieved source","accessibilityWorkforceImplications":"Staff who built agents need retraining on Agent Builder; users need new access points in Teams and SharePoint pages.","procurementImplications":"Copilot Chat-only populations using SharePoint-grounded agents may shift from free use to metered Copilot Credits, which needs budget and cost controls.","operatingModelImplications":"Agent lifecycle moves into central Microsoft 365 agent management, which pushes institutions to assign owners and review agents regularly.","sourceVerification":{"openedUrl":"https://techcommunity.microsoft.com/blog/MicrosoftMissionCriticalBlog/sharepoint-agents-are-changing-what-customers-need-to-know-for-preparation/4568460","referenceExcerpt":"Agent Builder does not automatically grant broad access to source files and folders; permissions may need to be updated for the intended audience.","promptVersion":"sled-research-v4.0","model":null,"basis":"agent-reported inspection"}}}]}
