What if extending Microsoft 365 Copilot wasn’t about adding features, but about building real enterprise agents that act on your business systems?

In this episode of Mastering AI with the Experts, I sit down with Sébastien Levert, Principal Product Manager at Microsoft working on Copilot extensibility and the Microsoft 365 agent platform.

We break down what Copilot agents actually are, what “extensibility” really means in concrete terms, and when low code stops being enough. We go deep into pro code tooling, engineering discipline, and what it takes to ship agents like real software inside Microsoft 365 Copilot.

This is not theory. It is architecture, workflow, and decision frameworks you can use immediately.

You’ll learn:

• What Copilot agents are beyond simple retrieval or Q&A
• The real difference between low code and pro code agents
• When to use Copilot Studio versus developer tooling
• Why building inside Microsoft 365 Copilot unlocks productivity context
• How to version, deploy, and roll back agents using CI/CD
• Why you usually do not want to build your own orchestration layer
• How WorkIQ changes the way developers build agents
• The enterprise signals that tell you it is time to move to pro code
• How to avoid painful rearchitecture later

Whether you are a business leader deciding where to invest, or a developer building scalable agent solutions, this episode will give you a clear framework for navigating Copilot extensibility the right way.
