Evaluate your M365 Copilot Agent options: SharePoint, Copilot Studio (Lite & Full), or Declarative Agents with the ATK?

You’ve rolled out Microsoft 365 Copilot, and now your organization has entered the AI revolution.

Mission accomplished! … or is it?

Out of the box, Microsoft 365 Copilot only has access to the underlying LLM’s baseline knowledge and some content in your Microsoft 365 tenant.

But most companies have valuable data outside Microsoft 365—manuals, standard operating procedures, policies, inventory systems, ERPs, CRMs, sales data, and more! How can you connect Copilot to these resources? Custom agents are the answer.

But, how do you choose between your agent options? SharePoint Agents, Agent Builder, Copilot Studio (Lite or Full), or Declarative Agents with the M365 Agents Toolkit (ATK)?

You know how!

You’ll attend this session and leave armed knowing the differences between these options and which one makes the most sense for your organization!
