What’s New in Copilot Studio: June 2025 Update

Microsoft’s Copilot Studio just got a major boost this June 2025. The latest update focuses on smarter agents, easier tool management, and deeper integration across Microsoft 365. Whether you’re a developer, admin, or power user, these features help you build more powerful AI agents that work seamlessly with your daily workflows.

Expanded Knowledge Sources for Smarter Agents

One of the biggest highlights is the enhanced agent builder within Microsoft 365 Copilot. Now, your AI agents can pull knowledge from Outlook emails, Teams messages—including group chats, channels, and meeting chats—and even files you upload directly.

This means less digging through endless threads and documents. Instead, your agents get a richer context to provide smarter, more relevant responses. The builder also suggests relevant knowledge sources based on your recent activity, speeding up the setup process.

“With just a few clicks, you can equip your agents with the same knowledge and context your team relies on to get work done.”

File Grouping: Organize Knowledge Like a Pro

File collections got an upgrade with the new file grouping feature, currently in preview. You can now group related files, name these groups, and add instructions that guide how your agent uses this knowledge.

For example, group HR policies separately from product docs and instruct the agent to reference only relevant groups based on context. This structured approach makes managing large knowledge bases in Microsoft Dataverse much easier and more transparent.

Tools Experience: Centralized and Intuitive

The new Tools tab unifies all your connectors and actions into a single, streamlined view. Whether you’re linking Outlook, SharePoint, SAP, or custom connectors, everything is now easier to find and configure.

Prebuilt connector actions let you add powerful capabilities with just a few clicks—like sending emails or updating records—without building from scratch. Plus, improved debugging tools and IntelliSense support help you troubleshoot faster.

Prompt Builder Gets Smarter and More Flexible

Prompt builders now support Microsoft Power Fx logic directly inside prompts. This lets you dynamically calculate values, format text, or reference memory tables without extra setup. Testing prompts is easier too, with batch evaluations and accuracy scoring now in public preview.

“You can now iterate faster, catch issues earlier, and deliver more reliable outcomes with less guesswork.”

Power Fx Regular Expressions for Advanced Text Handling

Parsing and validating text just got a lot easier. Copilot Studio now supports industry-standard regex within Power Fx formulas. This upgrade lets your agents extract tracking numbers, validate emails, or parse complex inputs with precision and less effort.

Regex support reduces the need for complicated text functions and can be reused across the Power Platform suite, making your AI workflows more robust and scalable.
