In this edition of our monthly roundup, we’re recapping new features in Microsoft Copilot Studio that were released in June 2025.
Copilot Studio agent builder enhancements in Microsoft 365 Copilot
Bring new knowledge to agents created in the agent builder
For many of us, critical knowledge is fragmented across various sources. It’s easy to find yourself digging through endless Microsoft Teams chats, email threads, and scattered SharePoint sites and documents to find the right piece of information. Emails hold key decisions and plans, Teams chats capture daily collaboration and contexts, and valuable files seem to be lost forever at the moment you need them most.
That’s why we’ve introduced powerful new knowledge sources in the Microsoft Copilot Studio agent builder embedded in Microsoft 365 Copilot. Your agents can now reference Outlook emails and Teams messages—including group chats, channels, meeting chats, and even files you upload directly.
Whether you’re in IT building a support agent trained on policy docs, internal email threads, and technical chat discussions, or a project manager automating reports pulled from daily team messages and inbox updates, you can now give your agents the ability to access a broader set of sources.
To make adding knowledge easier than ever, the builder also suggests relevant knowledge sources based on your recent activity and queries. This helps you identify and connect the right data more quickly. With just a few clicks, you can equip your agents with the same knowledge and context your team relies on to get work done.
These features are generally available now for all users with a Microsoft 365 Copilot Chat license or an active pay-as-you-go plan. Open the agent builder and try them out today, and infuse your agents with even more knowledge to help you move faster, work smarter, and stay informed. Learn more.
Organize knowledge and guide agent responses with file grouping
Earlier this year, we introduced file collections, which give makers the ability to upload multiple files as knowledge sources for their agents. Now, we’re expanding that functionality with file grouping, a new capability (now in preview) that helps you better organize files and fine-tune how your agent uses them.
With file grouping, you can now name and describe your file sets and, more importantly, provide group-specific instructions that guide your agent’s retrieval behavior. This makes it easier to tailor responses based on use case, document type, or even user role without needing to change the content itself.
For example, you might group together internal HR policies, product-specific documentation, or region-specific guides, and tell the agent to only reference that group when certain variables are met. It’s a more structured, transparent way to manage uploaded knowledge, and it makes your large Microsoft Dataverse knowledge bases easier to navigate and control.
To try it out, go to “Add Knowledge” in Copilot Studio and upload two or more files. You’ll see a toggle to enable grouping, along with options to name the group and set instructions. Learn more.
Copilot Studio enhancements for makers
Build and configure powerful agents with the new Tools experience
Tools give agents their power and determine what tasks they can handle as well as what actions they can perform. A new, streamlined Tools tab experience now makes it easier for makers to discover, configure, and manage everything agents need to get work done.
You can now access all your tools in one place. Whether you’re connecting to Outlook, SharePoint, SAP, Snowflake, custom connectors, or Microsoft Power Automate flows, you’ll now find everything in a single, unified view. This includes custom connectors and Model Context Protocols (MCPs) built for your organization.
You’ll also enjoy a more intuitive experience for discovering and adding prebuilt connector actions. Using prebuilt connector actions means you don’t have to build your own from scratch. With just a few clicks, you can set up agents to perform meaningful actions—like sending an email, updating a record, or scheduling a meeting—across Microsoft 365 (including Teams and Outlook), Dataverse, and other services.
Exploring available tools is easier, too. You can see all tools associated with each connector, helping you determine how these capabilities can work together across systems.
Tool configuration has also improved, with enhanced input widgets like calendar controls, file pickers, and time zone selectors. The tab also integrates with IntelliSense to help you configure tools more efficiently, and if a tool is not performing the way you expect, there’s now improved debugging tools like error messages. This will make it much easier to quickly identify and resolve issues with your tools like flows, connector actions, MCPs, and more.
Altogether, the new Tools experience gives you a more centralized, intuitive view that reduces friction when connecting tools, knowledge sources, topics, and flow. All this is designed to make it easier to build the agents you want, with the capabilities they need. Learn more.
Add logic and test your prompts directly inside the prompt builder
The prompt builder tool in Copilot Studio allows makers to create reusable, modular prompts that guide an agent to perform a specific task, such as summarizing, classifying, or extracting information. Assigned to agents or flows, prompts enhance reasoning and output quality for the user. The prompt builder tool has two new features designed for you to enrich and validate your prompts without ever leaving the editor.
You can now add Microsoft Power Fx logic directly inside your prompt inputs. This lets you dynamically calculate values, format or search text, manipulate collections, and more. You can do all this without setting up separate variables. For example, you can insert the current date, clean up messy input, or reference memory tables to ground the prompt with relevant context. Just type “/” or use “+Add content” to bring in a formula. It’s all the flexibility of Power Fx, now right where you need it. Learn more.
We’re also introducing prompt evaluation and testing in prompt builder, now in public preview. You can upload or generate test cases and run them in batches. Choose evaluation types like semantic similarity or JSON match, then review accuracy scores and detailed results. Each test run is saved so you can track performance over time. It’s a simple, scalable way to improve prompt quality without any custom tooling or manual experimentation required. From the prompt list, simply click the “…” menu and choose “Test” to get started. Learn more.
These updates turn the prompt builder into a more powerful end-to-end workspace. Whether you’re creating prompts that drive critical business workflows or experimenting with new agent behaviors, you can now iterate faster, catch issues earlier, and deliver more reliable outcomes with less guesswork. It’s everything you need to go from idea to tested, production-ready prompt, all in one place.
Validate and extract text with Power Fx regular expressions
Parsing and validating text just got a major upgrade in Copilot Studio. You can now use industry-standard regular expressions in Power Fx formulas to match, extract, and work with complex text patterns.
Regular expressions (regex) offer a compact and powerful way to describe how a text pattern should be matched. They allow you to perform text validation and extraction. If your agents rely on pulling out details from user input, like extracting tracking numbers, validating email addresses, or calculating durations from structured text, this update is for you. Makers who work with integrations, dynamic data inputs, or more advanced business logic will especially benefit from the precision and flexibility that Power Fx regular expressions provide.
Before this update, these kinds of tasks required long chains of text functions or limited entity configurations. Now, with support for IsMatch, Match, and MatchAll, you can achieve the same results with less effort. You can even reuse expressions across the Microsoft Power Platform suite.
Regular expressions may seem intimidating if they’re new to you, but the results are powerful. Find full details, syntax tips, and examples on Microsoft Learn. Then, start exploring the many ways Power Fx regular expressions can enhance your agents’ functions and responses. Learn more.
Streamline connections with in-chat single sign-on (SSO)
For users, setting up connections to services used by knowledge, tools, topics, and agent flows is also easier thanks to in-chat single sign-on (SSO), now in preview. When a user needs to access additional services that require credentials during an agent chat, the agent can automatically authenticate those other services. Instead of opening a separate Connection Manager page and jumping between windows, the agent prompts the user with an adaptive card for one-click approval. The agent makes the connection on the user’s behalf and uses that connection to continue responding to the user’s prompt.
Use any Copilot Studio-supported language with generative orchestration
Generative orchestration in Copilot Studio is now available in all Copilot Studio-supported languages beyond English (US). This is a major step toward making advanced AI capabilities accessible to makers and users around the world.
Until now, generative orchestration was only available for agents built in English (en-US). With this update, you can build agents in your preferred language and still take full advantage of features like natural language reasoning, dynamic workflows, and data-aware actions. You can also test and validate orchestration behavior in different languages, helping ensure your agent responses are high quality and contextually accurate across languages before you publish.
If you’re building connected agents, there’s more good news: when a handoff occurs from one agent to another, the orchestrator seamlessly continues the conversation in the user’s language—no additional language configuration is required in the target agent. This makes it easier to scale multilingual solutions without duplicating setup across your connected agent ecosystem.
This update is now in public preview across all regions and languages supported by Copilot Studio. To try it out, simply enable generative orchestration in your agent. You can either set a non-English primary language when creating the agent, or add additional languages via settings once orchestration is turned on. Learn more.
Analyze knowledge use in autonomous agents, insights for unanswered questions
Agent analysis just got more insightful in Copilot Studio thanks to two exciting new features. These insights help you better understand how your agents perform and identify areas where there is room to improve.
Agents with autonomous capabilities (through triggers) have provided run history analytics in the Activity tab. Now, makers can garner additional new insights with knowledge source analysis. This feature, now generally available, lets you see how your autonomous agents and agent flows used the knowledge they’re grounded in during each run. These metrics help you assess relevance, adjust content, and improve performance over time. It’s a valuable new lens into what’s working inside your autonomous agents while they’re working for you.
Makers can also now view where user questions went unanswered. This happens either because the agent didn’t have the knowledge available to identify an appropriate response, or because there was not a topic configured to handle the query. Now, the list of unanswered questions is categorized into themes and conversation contexts. No more combing through old conversations or building more spreadsheets—the Copilot Studio Analytics page automatically highlights patterns and clusters these topics where responses fell short. These insights, found in the Knowledge section on the page, make it easier to close content gaps and continuously refine your agents. This feature is currently in preview and will appear automatically for qualified customers.
These two features help you turn metrics into a data-driven feedback loop. Pinpoint what’s working, where content can improve, and how to make your agents more effective over time. With every run and agent interaction, you can gain deeper actionable insights to help you improve your agent.
Microsoft Power Platform admin center enhancements for admins
Track usage, manage agents, and allocate capacity
As your organization builds more agents in Copilot Studio, keeping track of them and understanding how they’re used becomes increasingly important. With new visibility and management tools in the Power Platform admin center (PPAC), admins can now support agent solutions at scale with far less manual effort.
The new agent inventory view provides admins with a tenant-wide list of all agents built in Copilot Studio. You’ll find key details like agent name, environment, owner, creation date, and status all in one place. No more checking each environment manually or stitching together spreadsheets. This supports smoother lifecycle management and more consistent agent experiences across teams. Learn more.
The new agent usage analytics experience takes this a step further. Admins can now explore tenant-level data that shows how agents are being used across the organization, including usage trends, billing metrics, and a curated list of top agents. It’s a major step forward in tracking usage and enabling cost control practices at the organization level—helping IT teams see what’s working, what’s underused, and where support is needed. Learn more.
Both features are available in the PPAC today for tenant and environment admins in commercial regions. To get started, enable tenant-level analytics in your environment. Then go to the PPAC, select the “New admin center,” and navigate to Manage > Copilot Studio.
