Microsoft 365 Copilot: New custom engine agents

Originally posted by Microsoft Jan 22, 2025 Uncategorized 0 Comments

Microsoft 365 Copilot introduces custom engine agents for domain or tenant-specific workflows, supported in Teams and soon in BizChat. Requires a Copilot license, with rollout starting February 2025. These agents enable unique AI experiences and can be created and deployed via Copilot Studio or Visual Studio.

We are thrilled to announce the upcoming rollout of custom engine agents in Microsoft 365 Copilot. These agents are specialized agentic solutions that can be built on any large language model (LLM), toolchain, or orchestration tool tailored for specific domain or tenant workflows. This feature is already supported in Microsoft Teams and will be available after this rollout in Microsoft 365 Copilot Business Chat (BizChat).

To access custom engine agents, your organization will need a Microsoft 365 Copilot license.

This message is associated with Microsoft 365 Roadmap ID 474439.

When this will happen:

Public Preview: We will begin rolling out early February 2025 and expect to complete in mid-March 2025.

General Availability (Worldwide): We will begin rolling out in late March 2025 and expect to complete by early April 2025.

How this will affect your organization:

Custom engine agents will empower your organization to create highly customized agentic experiences that leverage your own AI systems and orchestrators. This means you can design unique prompts, connect to any LLM, and integrate these custom agents with Microsoft 365 Copilot.

After this rollout, all users or specific users will be able to access the agents, provided the agents have been enabled and deployed in the Microsoft 365 admin center > Copilot tab.

Creating custom engine agents

Eligible users, or those designated by you, will have the capability to create agents using Microsoft Copilot Studio for low-code tools or the Microsoft Teams Toolkit in Microsoft Visual Studio for pro-code solutions. Users can access Copilot Studio only if you have enabled the Microsoft Power Automate free license for them.

Developers can also use the Teams Toolkit in Visual Studio and the Teams AI Library for pro-code solutions to build these agents from scratch.

Deploying custom engine agents

All the familiar admin deployment and management controls in the Microsoft 365 admin center for declarative agents will seamlessly transition to custom engine agents:

Custom engine agents created using Copilot Studio can be deployed by users for their individual work-related tasks. Also, users have the flexibility to share these agents with internal teams, contingent on the settings you configure in the Microsoft 365 admin center > Teams applications > Shared Copilot applications. Organization-wide sharing requires admin approval through the Microsoft 365 admin center.

Custom engine agents created or updated using the Teams Toolkit in Visual Studio and the Teams AI Library requires admin approval and admin deployment in the Microsoft 365 admin center.

What you need to do to prepare:

This rollout will happen automatically by the specified date with no admin action required before the rollout. Review your current configuration to determine the impact for your organization. You may want to notify your users about this change and update any relevant documentation.
