5 Things You Should Know About Agentic AI at Work

If you’ve been paying attention to what Microsoft and Anthropic have shipped in 2026, you’ve probably noticed the conversation has shifted. We’re no longer talking about chatbots that answer questions. We’re talking about agentic AI, tools that plan, execute, and complete multi-step workflows on your behalf.

Anthropic’s Claude Cowork launched in January as a desktop agent for knowledge workers. Two months later, Microsoft folded that same technology into Microsoft 365 as Copilot Cowork, wrapping Anthropic’s Claude agent architecture in Microsoft’s cloud infrastructure, enterprise governance, and deep integration with the apps most organizations already use. It’s a multi-model play. Microsoft isn’t betting on one AI provider. They’re choosing the right model for the job, and for agentic workflows, that model is Claude.

The result is something neither company could have delivered alone: Anthropic’s agentic intelligence running inside the Microsoft 365 ecosystem you already know. If you’re a knowledge worker trying to separate what’s real from what’s hype, here are five things worth understanding.

1. This Is Not the AI You Used Last Year

The biggest shift is what “agentic” actually means. In 2025, you asked a question, got an answer, and did the work yourself. That was useful, but it was still call-and-response.

Agentic AI is different. You describe an outcome, and the tool figures out the steps. Copilot Cowork takes multi-step actions directly inside Word, Excel, and PowerPoint, while also bringing Claude’s desktop agent capabilities into the mix, reading, editing, and creating files across multi-step workflows without you hovering over every action. Instead of “summarize this document,” you can say “review these three reports, pull out the conflicting data points, and draft a summary email with recommendations.” That’s a fundamentally different kind of task.

2. Connectors and Plugins Are What Make It Useful

Out of the box, Copilot Cowork is impressive but limited. The real value unlocks when you connect it to the tools you already use.

On the Microsoft side, Copilot draws from the Microsoft Graph, giving it native access to your emails, calendar, files, Teams conversations, and SharePoint content. The Claude layer brings MCP connectors and plugins, linking to external services like Gmail, Google Drive, Slack, Notion, and DocuSign, with pre-built plugin bundles for legal, sales, finance, marketing, and more.

Together, they give you reach into both your Microsoft 365 ecosystem and the broader toolset your teams actually work with every day. That combination is where the real utility lives.

3. You Can Teach It How You Work

This is the part most people skip, and it’s the part that makes the biggest difference.

Copilot Cowork learns from your organizational context through Microsoft IQ, the layer that feeds agents workplace knowledge from M365 signals and business data from Fabric. Copilot Studio lets teams build custom agents without code. On the Claude side, Skills let you define instruction files for your preferences, processes, and standards, from brand voice to report formatting to review checklists.

The more you invest in teaching the tool how you work, the more it stops feeling like a generic AI and starts feeling like a trained team member. Most people never get past the default experience, and then wonder why AI feels underwhelming.

4. Your Data Strategy Determines Your AI Ceiling

Agentic AI is only as good as the data it can access, and only as trustworthy as the governance around that data.

If your files are scattered across personal drives, random SharePoint sites, and email attachments, these tools are reasoning over chaos. Organizations that have invested in information architecture, clean folder structures, consistent naming, proper metadata, are the ones seeing real returns. AI has raised the stakes. The cost of bad data practices is no longer “I can’t find the file.” It’s “the AI gave leadership a recommendation based on an outdated spreadsheet.”

Before you spend time tweaking prompts or installing plugins, get your data house in order. That’s where the real ROI lives.

5. Start With One Workflow, Not an Entire Transformation

The fastest way to burn out on agentic AI is to overhaul your entire workday at once. The people getting the most value started small. One repeatable workflow. One pain point. A weekly status report. Client call prep. A recurring deliverable that follows the same structure every time.

Pick one thing. Set it up properly. Connect it to the right data. Run it for a few weeks. Refine it. Then expand. Copilot Cowork rewards deliberate, incremental adoption over big-bang deployments.

The AI Showed Up. Did You?

Agentic AI is real, and it’s maturing fast. Microsoft and Anthropic brought different strengths to the table and built something better together: AI that doesn’t just help you think, but helps you do.

The knowledge workers who will benefit most aren’t chasing the newest features. They’re doing the fundamentals well. Clean data. Clear processes. Intentional adoption. The tools are ready. The question is whether you are.
