Microsoft 365 AI agents — built with Copilot Studio — work autonomously: they approve expenses, onboard new clients, and triage hundreds of emails without human involvement at every step. For SMEs, this is not science fiction. It is a competitive advantage available today. ## From reactive AI to autonomous AI: what changed in 2026 For years, AI tools worked as response assistants: you asked a question, the AI answered. Useful, but limited. The real leap came with the shift to autonomous agents — systems that receive a goal, plan the necessary steps, and execute them without waiting for constant instructions. Microsoft calls this evolution Agentic AI and built it directly into the Microsoft 365 ecosystem. The result: any company with an M365 licence now has access to tools to build agents that work around the clock, without typos, without skipping steps, without needing reminders. Key insight: An AI agent does not replace employees — it frees them from repetitive tasks so they can focus on decisions that genuinely require human judgement. ## What is an AI Agent and how does it work in the Microsoft ecosystem An AI agent in the Microsoft context is a programme configured in Copilot Studio that combines three capabilities: - Natural language understanding — interprets requests in everyday language, such as “approve João’s expense if it is under €200” - Access to business data — connects to SharePoint, Dataverse, Teams lists, email, or external systems via connectors - Action execution — triggers Power Automate flows, updates records, sends notifications, creates Planner tasks Unlike a traditional chatbot, which responds but does not act, an agent executes. Unlike a simple Power Automate flow, which follows a rigid sequence, an agent adapts to context — if a request is incomplete, it asks for the missing information; if a condition is not met, it escalates to the right person. ### The three components of a Microsoft agent - Copilot Studio — the agent authoring environment, no code required - Power Automate — executes the concrete actions (create record, send email, update sheet) - SharePoint / Dataverse — stores the data the agent queries and updates ## 3 concrete use cases for SMEs ### Expense approval without email chains The current problem: an employee submits an expense report by email. The manager is in a meeting and forgets. The accounting team chases the approver three days later. The process takes a week and leaves no audit trail. With an agent: the employee fills in a simple form. The agent automatically checks whether the expense is within company policy, sends an Adaptive Card in Teams to the manager for one-click approval, logs the result in SharePoint, and notifies accounting — all in under five minutes. Typical impact: 80% reduction in expense processing time. Complete audit trail with no manual work. ### Client onboarding without constant intervention The current problem: every new client requires someone from the team to collect documents, create folders, send welcome messages, configure accesses, and schedule the kick-off meeting. The process varies depending on who is available and information gets lost. With an agent: when the CRM registers a new client, the agent automatically executes the entire sequence: creates the client folder in SharePoint with the correct structure, sends the personalised welcome email, requests the necessary documents via form, creates onboarding tasks in Planner, and schedules the kick-off meeting based on the team’s availability. Typical impact: client onboarding running in 15 minutes instead of two days. Zero variation between clients. ### Email triage and intelligent routing The current problem: the company’s general inbox receives dozens of emails per day — support requests, commercial enquiries, invoices, spam. Someone has to read everything and route it manually. With an agent: the agent reads each incoming email, classifies the intent (support, commercial, finance, other), extracts the relevant information, and routes it to the correct team with a context summary. Urgent requests are flagged and escalated automatically. Typical impact: elimination of 2 to 3 hours of daily manual triage. Faster response to urgent requests. ## How to get started: Copilot Studio + Power Automate + SharePoint Implementing a first agent requires no dedicated IT team and no months of development. The process has four phases: - Identify the process — choose a repetitive process with clear steps and structured data - Map the logic — define the conditions, actions, and exceptions of the process - Build in Copilot Studio — configure the agent visually, without code, connecting to existing systems - Test and deploy — validate with real cases before activating for the whole team The technical prerequisite is straightforward: a Microsoft 365 licence with Copilot Studio (included in several plans or available as an add-on). Data needs to be in Microsoft systems — SharePoint, Dataverse, or Exchange. ### What not to do - Do not start with the company’s most complex process - Do not try to automate a process that nobody can describe consistently - Do not ignore exception handling — the agent needs to know what to do when something goes wrong ## What AvantIT can build for you in 4 weeks At AvantIT, we implement Microsoft agents in SMEs following a structured process: - Week 1: discovery session — we identify the 3 processes with the greatest automation potential - Week 2: agent design — we map the logic, required data, and integrations - Week 3: build and test — we develop the agent in Copilot Studio with Power Automate - Week 4: training and activation — we train the team and activate in production with support The result: a functional agent in production in 30 days, with documented processes and a team ready to scale.
