Discover new AI powered business Certifications to validate the skills that matter most. Gretchen LaBelle: Copilot + Agents Learning Portfolio Manager, Global Skilling Tarek Saleh Eldin: Content Publishing Manager, Global Skilling In Part 1 of this series, The AI job boom is here. Are you ready to showcase your skills?, we explored how Microsoft Certifications across AI, cloud, and security are evolving to keep pace with a rapidly changing job market. AI is no longer a niche capability. It’s becoming foundational across roles, reshaping how work gets done, and redefining how professionals create impact. This post picks up that thread. As organizations move from experimenting with AI to operationalizing it at scale, big changes are happening in business solutions roles. These shifts demand the ability to apply AI in real business contexts, redesign processes, build intelligent apps and agents, and lead transformation responsibly across the organization. Earlier this year, Microsoft introduced four new AI business solutions Certifications: Microsoft Certified: Agentic AI Business Solutions Architect (Exam AB‑100) Microsoft 365 Certified: Copilot and Agent Administration Fundamentals (Exam AB‑900) Microsoft Certified: AI Business Professional (Exam AB‑730) Microsoft Certified: AI Transformation Leader (Exam AB‑731) Together, these Certifications map to the critical roles in an AI‑driven workplace, from business practitioners and IT administrators to solution architects and transformation leaders. Building on that foundation, we’re launching new Certifications to help amplify human skills for AI-powered roles in the business landscape.

Navigating the transition: FAQs The following questions and answers can help you determine how these retirements and expanded portfolio could impact your learning journey: Q. Why is Microsoft implementing these updates? A. Microsoft Credentials are valuable, as is the time you spend earning them. With the ongoing evolutions in technology, it’s essential that we keep the credentials up to date so we can help you stay aligned with latest skills and trends. We’re implementing these updates to provide a valuable path forward to keep up with the latest skills. Q. I’ve already earned one of the retiring Certifications. What happens now? A. If you’ve already earned any of the retiring Certifications, your credential remains valid until it expires. Retirement does not revoke or invalidate Certifications that were earned while the exam was active. They show your continued dedication to staying up to date and learning new skills in this ever-changing technical landscape. Q. What if a Certification that’s retiring is part of the prerequisites for an expert-level Certification? A. If a retiring Certification is required for an expert-level Certification, the requirements for that expert-level Certification will be updated as needed. The retiring Certification will be removed from the requirements and replaced (as appropriate) with a new associate-level Certification. If you’ve earned an expert-level Certification by earning an associate-level Certification that’s now retiring, you’ll continue to hold the expert-level Certification as long as you renew the expert-level Certification when it’s eligible. After you’ve earned a Certification, and if you renew it when it’s eligible, you hold it until it expires. If you’ve earned an associate-level Certification that’s a requirement for an expert-level Certification and that associate-level Certification hasn't expired, it can still satisfy the expert-level requirement. Be sure to meet all the requirements for the expert-level Certification before the associate-level Certification expires. Expired Certifications cannot be used to meet the requirements for an expert-level Certification. Q. Can I renew a soon-to-retire Certification? A. Yes, as long as it’s eligible for renewal and you renew it before the Certification officially retires, you can renew a soon-to-retire Certification. Please note that Fundamentals Certifications don’t expire. Q. Is there a direct transition path from a retiring Certification that I’ve already earned to the related new Certification, or do I need to pass the new exam? A. To earn the new Certification, you need to pass the new exam, since the new exam and the old one don’t measure the same skill sets. Q. I’m preparing for an exam that’s retiring. What should I do? A. The time you spend preparing for an exam and earning a Certification never goes to waste. If you’re actively preparing for an exam that’s retiring and a replacement exam has been announced: If you’ve already registered for the exam, you can continue preparing for it and take it while it’s still available. Keep in mind that after the exam retires, you won’t be able to retake it if you don’t pass, and you won’t be able to renew it. Exam registration ends on the same day that the exam retires. If you haven’t registered for the exam and there’s a related new exam, we strongly recommend that you prepare for and take the new exam instead, as noted in the following table. If you’re not close to testing for this exam Prepare for and take this exam instead Learning path and instructor-led training expected to be available in Exam MB-280 Exam AB-210 April 2026 Exam PL-200 Exam AB-410 April 2026 If you’re preparing for Exam PL-900 to earn the Microsoft Certified: Power Platform Fundamentals Certification, the new Course PL-900 will be available at the end of June 2026. If you’re preparing for Exam MB-335 to earn the Microsoft Certified: Dynamics 365 Supply Chain Management Functional Consultant Associate Certification, Exam MB-700 to earn the Microsoft Certified: Dynamics 365: Finance and Operations Apps Solution Architect Expert Certification, or Exam PL-600 to earn the Microsoft Certified: Power Platform Solution Architect Expert Certification, consider preparing for and taking Exam AB-100 to earn the Microsoft Certified: Agentic AI Business Solutions Architect Certification, the new flagship expert‑level Certification for solutions architects, available now. Note that to earn the Certification, you must pass Exam AB-100 and you must also have a current associate-level Certification. Q. How might these updates impact partner competency requirements? A. To track whether and how these updates might impact partner competency requirements, go to Solutions Partner for Business Applications in the Partner Center. The bigger picture AI is transforming not only what technology can do but also who does the work and how. Whether you’re building agents, designing intelligent apps, transforming sales, or leading enterprise AI strategy, there’s now a Certification that reflects the real skills your role demands. These Certifications can help ensure that you’re not only ready for AI-driven work but you’re also leading it. We’ll share updates for the new AI business solutions Certifications, including beta exams and go-live dates, on The Skills Hub Blog. Stay tuned!

SharePoint lists with Copilot Studio error
I’m seeing a persistent issue when integrating SharePoint lists with Copilot Studio agents. Any SharePoint list I add to an agent results in an error being shown in the Copilot Studio UI, but no error message, diagnostic detail, or failure reason is surfaced. I’ve removed and re-added the list connections multiple times and reproduced the issue across multiple agents, with the same outcome each time. Has anyone encountered this behaviour, or are there known issues or prerequisites (e.g. permissions, connector state, tenant configuration, or recent service changes) that could cause silent failures when integrating SharePoint lists?Welcome let's get started

From the Field: Why This Integration Works As an experienced AI Cloud Solution Architect working in Greater China Region (GCR), I’ve seen one emerging pattern that delivers quick wins for some of my customers: combining Microsoft Copilot Studio with an existing Azure AI Search index. Teams choose this approach because it delivers two outcomes immediately: business users get grounded, reliable answers, and enterprises avoid re-building pipelines or re-platforming knowledge stores. This guide shows exactly how to connect Copilot Studio to an Azure AI Search index that is already live, so your copilot can answer confidently using your enterprise documents. What We Assume Is Already Ready To stay focused on the integration step, we assume: You have an Azure AI Search service deployed You have an index containing vectorized content (manuals, PDFs, policies, FAQs) Your platform/data team already handled ingestion, embeddings, and indexing In short, your Azure AI Search endpoint and admin key are ready, and the index already contains chunked content with embeddings. Step 1 - Collect Your Azure AI Search Connection Details From the Azure AI Search resource: Endpoint URL Azure AI Search → Overview → Url: https://<your-search-service>.search.windows.net Admin Key Azure AI Search → Keys Use either the primary or secondary key. Governance tip: For production, rotate keys regularly and use managed identities when possible. Step 2 - Add Azure AI Search as Knowledge Inside Copilot Studio Open your Copilot Studio agent Go to the Knowledge tab Select Add knowledge, choose Azure AI Search Provide: Endpoint URL Admin key Create or select the connection Choose your existing index from the dropdown Select Add to agent Step 3 - Test a Grounded Response Open the Test copilot pane and ask a question your indexed content can answer, such as: “What are the different licensing options available for Power Platform?” Verify that: The Activity Map shows Azure AI Search being invoked The answer reflects the correct document in your index Citations or references appear where applicable Conclusion Business value: You can activate grounded, explainable answers in Copilot Studio immediately by reusing your existing Azure AI Search index - no re-platforming, no new pipelines. Team model: Data/Platform teams own ingestion, enrichment, and vectorization. Business teams build and refine the copilot experience in Copilot Studio. Scale and governance: All components stay inside Azure, with enterprise-grade security, RBAC, and operational monitoring, while enabling low‑code agility for makers.

🔍 1. Why Evaluating LLM Responses is Hard In classical programming, correctness is binary. Input Expected Result 2 + 2 4 ✔ Correct 2 + 2 5 ✘ Wrong Software is deterministic — same input → same output. LLMs are probabilistic. They generate one of many valid word combinations, like forming sentences from multiple possible synonyms and sentence structures. Example: Prompt: "Explain gravity like I'm 10" Possible responses: Response A Response B Gravity is a force that pulls everything to Earth. Gravity bends space-time causing objects to attract. Both are correct. Which is better? Depends on audience. So evaluation needs to look beyond text similarity. We must check: ✔ Is the answer meaningful? ✔ Is it correct? ✔ Is it easy to understand? ✔ Does it follow prompt intent? Testing LLMs is like grading essays — not checking numeric outputs. 🧠 2. Why RAG Evaluation is Even Harder RAG introduces an additional layer — retrieval. The model no longer answers from memory; it must first read context, then summarise it. Evaluation now has multi-dimensions: Evaluation Layer What we must verify Retrieval Did we fetch the right documents? Understanding Did the model interpret context correctly? Grounding Is the answer based on retrieved data? Generation Quality Is final response complete & clear? A simple story makes this intuitive: Teacher asks student to explain Photosynthesis. Student goes to library → selects a book → reads → writes explanation. We must evaluate: Did they pick the right book? → Retrieval Did they understand the topic? → Reasoning Did they copy facts correctly without inventing? → Faithfulness Is written explanation clear enough for another child to learn from? → Answer Quality One failure → total failure. 🧩 3. Two Types of Evaluation 🔹 Intrinsic Evaluation — Quality of the Response Itself Here we judge the answer, ignoring real-world impact. We check: ✔ Grammar & coherence ✔ Completeness of explanation ✔ No hallucination ✔ Logic flow & clarity ✔ Semantic correctness This is similar to checking how well the essay is written. Even if the result did not solve the real problem, the answer could still look good — that’s why intrinsic alone is not enough. 🔹 Extrinsic Evaluation — Did It Achieve the Goal? This measures task success. If a customer support bot writes a beautifully worded paragraph, but the user still doesn’t get their refund — it failed extrinsically. Examples: System Type Extrinsic Goal Banking RAG Bot Did user get correct KYC procedure? Medical RAG Was advice safe & factual? Legal search assistant Did it return the right section of the law? Technical summariser Did summary capture key meaning? Intrinsic = writing quality. Extrinsic = impact quality. A production-grade RAG system must satisfy both. 📏 4. Core RAG Evaluation Metrics (Explained with Very Simple Analogies) Metric Meaning Analogy Relevance Does answer match question? Ask who invented C++? → model talks about Java ❌ Faithfulness No invented facts Book says started 2004, response says 1990 ❌ Groundedness Answer traceable to sources Claims facts that don’t exist in context ❌ Completeness Covers all parts of question User asks Windows vs Linux → only explains Windows Context Recall / Precision Correct docs retrieved & used Student opens wrong chapter Hallucination Rate Degree of made-up info “Taj Mahal is in London” 😱 Semantic Similarity Meaning-level match “Engine died” = “Car stopped running” 💡 Good evaluation doesn’t check exact wording. It checks meaning + truth + usefulness. 🛠 5. Tools for RAG Evaluation 🔹 1. RAGAS — Foundation for RAG Scoring RAGAS evaluates responses based on: ✔ Faithfulness ✔ Relevance ✔ Context recall ✔ Answer similarity Think of RAGAS as a teacher grading with a rubric. It reads both answer + source documents, then scores based on truthfulness & alignment. 🔹 2. LangChain Evaluators LangChain offers multiple evaluation types: Type What it checks String or regex Basic keyword presence Embedding based Meaning similarity, not text match LLM-as-a-Judge AI evaluates AI (deep reasoning) LangChain = testing toolbox RAGAS = grading framework Together they form a complete QA ecosystem. 🔹 3. PyTest + CI for Automated LLM Testing Instead of manually validating outputs, we automate: Feed preset questions to RAG Capture answers Run RAGAS/LangChain scoring Fail test if hallucination > threshold This brings AI closer to software-engineering discipline. RAG systems stop being experiments — they become testable, trackable, production-grade products. 🚀 6. The Future: LLM-as-a-Judge The future of evaluation is simple: LLMs will evaluate other LLMs. One model writes an answer. Another model checks: ✔ Was it truthful? ✔ Was it relevant? ✔ Did it follow context? This enables: Benefit Why it matters Scalable evaluation No humans needed for every query Continuous improvement Model learns from mistakes Real-time scoring Detect errors before user sees them This is like autopilot for AI systems — not only navigating, but self-correcting mid-flight. And that is where enterprise AI is headed. 🎯 Final Summary Evaluating LLM responses is not checking if strings match. It is checking if the machine: ✔ Understood the question ✔ Retrieved relevant knowledge ✔ Avoided hallucination ✔ Provided complete, meaningful reasoning ✔ Grounded answer in real source text RAG evaluation demands multi-layer validation — retrieval, reasoning, grounding, semantics, safety. Frameworks like RAGAS + LangChain evaluators + PyTest pipelines are shaping the discipline of measurable, reliable AI — pushing LLM-powered RAG from cool demo → trustworthy enterprise intelligence.
