What’s New in Notebooks | June 2026

ezrapark — Thu, 11 Jun 2026 15:03:45 GMT

Today, Copilot Notebooks is rolling out to more people across your team, making shared notebook collaboration broadly accessible in the Microsoft 365 Copilot app and OneNote.

Copilot Notebooks are available to Copilot Chat users

Previously only available to Microsoft 365 Copilot users, Copilot Notebooks is now rolling out to Copilot Chat users, giving more people across the team a shared place to gather project context, work from reference sources, and turn that information into helpful mind maps and learning tools in study guide.

This gives Copilot Chat users a powerful workspace for knowledge sharing and collaboration: they can add files — including Word documents, PowerPoint presentations, Excel worksheets, and Outlook emails — into a notebook, ask questions across those sources, and understand content through mind maps and learning tools in study guide.

In mixed-licensed teams, everyone can collaborate in the same notebook¹, while Microsoft 365 Copilot users can add premium sources and use premium AI capabilities, like advanced creation experiences.

Starting today, Copilot Chat users can explore Copilot Notebooks in the Microsoft 365 Copilot app and in OneNote².

Availability: Rolling out to Copilot Chat commercial and education users² starting today.

Learn more about Copilot Notebooks and this change in our Support documentation. For more information for education users², read the Copilot Notebooks in Education blog.

¹Copilot Chat users have limited sources per notebook, access to standard sources only, and standard access to chat.

²Only Copilot Notebooks in OneNote on web will be available to Copilot Chat (Basic) commercial customers at this time.

Copilot and DLP policy behaviours

manojviduranga — Thu, 11 Jun 2026 12:55:48 GMT

Hi Copilot Brain Trust,

Looking for some real-world experiences with Microsoft 365 Copilot DLP enforcement.

We've implemented a DLP policy targeting the Microsoft 365 Copilot location with the action to prevent Copilot from processing content that contains our sensitivity label (restricted).

The implementation is based on the following Microsoft documentation:

DLP for Microsoft 365 Copilot: https://learn.microsoft.com/en-us/purview/dlp-microsoft365-copilot-location-learn-about

Create DLP policies for Microsoft 365 Copilot: https://learn.microsoft.com/en-us/purview/dlp-microsoft365-copilot

Microsoft documentation states that when a DLP policy blocks Copilot processing, protected content should not be processed or used in Copilot-generated responses (although citations may still appear).

However, during testing we're observing scenarios where Copilot appears to access/process provide restricted snippet with file names from content that should be protected by the DLP policy.

A few questions for anyone who has implemented this in production:

Have you successfully validated DLP policies preventing Copilot from summarising sensitivity-labelled content?

Are there any known delays between policy deployment and enforcement?

Have you observed differences between Copilot Chat and Copilot experiences within Word, Excel, or PowerPoint?

Are there any prerequisites, limitations, or known issues not currently reflected in the public documentation?

I'm interested to hear whether others have seen similar behaviour or have successfully validated this scenario end-to-end.

Thanks in advance.

End users not seeing the option "Select Brand" from PowerPoint Copilot

unslog — Thu, 11 Jun 2026 09:09:04 GMT

Hello

I have followed the instructions in this guide https://learn.microsoft.com/en-us/microsoft-365/copilot/enterprise-brand-manager to push out a brand kit to end users, however very frustratingly, users do not have access to the "Select Brand" option within PowerPoint Copilot setting (i.e. PowerPoint.Cloud.Microsoft web instance)

Steps i performed over a week ago!

1- Enabled enterprise Brand Manager policy - Config.office.com

2. Created a Brand Kit ( https://m365.cloud.microsoft > Waffle Menu > Create > More... > Brand Kits. Ensured it's published adn Official)

3. Brand kit is published and Official, see below

* Screenshot place holder - Forbidden by microsoft! *

I have tested this on over three different users via PowerPoint.Cloud.Microsoft and desktop app

All of these users have Copilot Premium licenses for more than a few months!

MY EXPERIENCE

I seem to be the only user that has this option "Seelct Brand";

* Screenshot place holder - Forbidden by microsoft! *

END USER EXPERIENCE

This is what the end user within the same tenancy, and is deffo logged into their business account;

* Screenshot place holder - Forbidden by microsoft! *

End users can access the Official Branding Kit;

This is becoming very frustrating and shoud just work!

Microsoft Cowork (Frontier) Scheduled Runs Can't Access Custom Plugins/MCP Tools

Farhan_akhtar — Thu, 11 Jun 2026 05:48:48 GMT

Hi everyone,

I'm currently building a ServiceNow incident handling automation using Microsoft Cowork (available through the Microsoft Frontier program) and have run into an issue that I haven't been able to resolve.

Solution Architecture

I have built:

A custom FastAPI MCP backend hosted on Azure Web App
MCP tools for:
- Fetching new ServiceNow incidents (state = new)
- Retrieving relevant ServiceNow Knowledge Base articles based on incident context
- Updating ServiceNow comments and work notes
- Performing Microsoft Entra ID automation (e.g., user profile updates requested through incidents)
Custom plugins and skills deployed through the Microsoft 365 Admin Center

What Works

When I start the Cowork agent manually and provide instructions such as processing new incidents:

It successfully discovers my custom tools.
It fetches incidents from ServiceNow.
It retrieves KB articles.
It updates work notes/comments.
It performs Entra ID actions when required.
It processes incidents sequentially according to the workflow.

So the overall integration appears to be working correctly.

The Problem

The issue occurs when I configure the Cowork agent to run on a scheduled basis (every hour).

Instead of executing the workflow, the agent reports messages like:

and after retries:

From the Workspace panel, I can see the scheduled task is active, but during scheduled execution it behaves as if none of the custom plugins, skills, or MCP tools are available in the session. And when I go to the same scheduled session and manually enter the same prompt which I had provided in the scheduled part, then it is working as expected.

Questions

Are scheduled Cowork runs executed in a different runtime/session context than manual runs?
Do scheduled runs currently support:
- Custom MCP servers?
- Custom plugins deployed through M365 Admin Center?
- Custom skills?
Are there any additional permissions, trust settings, or plugin approvals required specifically for scheduled executions?
Has anyone successfully used scheduled Cowork tasks with custom MCP tools or external systems such as ServiceNow?
Is this a known limitation of the current Frontier preview?

Any guidance or confirmation from others using Cowork + MCP integrations would be greatly appreciated.

Thanks!

The Windows App isn't viable at present

jmachats — Tue, 09 Jun 2026 16:56:03 GMT

The Windows Copilot app is not viable for real work because it only stores three conversations.

Edge Copilot and the mobile app preserve full history and sync across devices, which makes them usable for long‑term projects.

The Windows app should match that behavior or be retired. The inconsistency breaks workflows for users doing multi‑month creative and strategic work.

Meet the new Copilot Studio: rebuilt for more complex, multi-step work

Ben Appleby — Thu, 11 Jun 2026 17:16:17 GMT

We consistently hear feedback from our customers. You want to build more capable agents and workflows that work together naturally. You need agents that can handle multi-step tasks reliably, without breaking down midway. You need more intuitive ways to build agents so you can scale your maker workforce. That feedback helped shape the exciting improvements we’re sharing today.

Starting now, customers can dive into the rebuilt, revamped Microsoft Copilot Studio. The new streamlined authoring experience and modern AI core make it easier to build agents and workflows that deliver more consistent and reliable outcomes. Teams can move faster and create solutions that hold up better in real-world use. This update is generally available worldwide, ready to create agents for production use.

Build more reliable agents

We’re making it easier to create agents that work the way you expect from the start. We've strengthened how agents follow instructions and handle complex tasks, leading to more consistent results for your business scenarios. The new building experience streamlines Copilot Studio to bring the essential configurations to the forefront, reducing configuration tabs from nine to four. Together, these improvements help make it faster to build agents that are more reliable, more capable, and more efficient.

The new experience includes:

New agentic orchestrator: Built on a new coding harness and CLI layer, the new orchestrator has stronger instruction adherence and long-horizon task execution. It supports recursive task execution, which enables the agents you create to be far better at working through complex and dynamic problems. It can also process large volumes of content and produce rich file outputs, opening up new document and data scenarios.
New agent building interface: The new interface helps make building agents faster and more streamlined, allowing you to see your instructions, skills, tools and knowledge in one place. The new modern full page testing experience features better formatting and inline chain-of-thought and tool calling.
Support for skills: Write your agent reusable instructions in markdown that can load on demand for completing specific tasks. You can also import skills you already have, including existing GitHub Copilot or Claude Code skills.

Try the new agent building designer in Copilot Studio.

Build more intelligent end-to-end workflows

Workflows are at the heart of reliable automation. With the new workflow designer, you can build intelligent, AI-driven processes in one place, combining structured workflow steps with agents.

New workflow designer: An intuitive visual designer for building agentic automations in a single, unified workspace. With node-by-node testing and robust versioning, it is now easier and faster to build, test, and publish running workflows.

Agent nodes: Call existing agents directly into a workflow. This allows you to leverage deterministic execution for reliability, while seamlessly handing off complex tasks that require greater intelligence and flexibility to agents within the workflow.

MCP servers: Connect to a broad ecosystem of model context protocol (MCP) server-enabled tools (preview). These allow workflows to execute tasks and involve users for approval, while staying within Microsoft security, permission, and compliance boundaries.

Get started today

These updates bring together the tools you need to modernize any business processes with AI onto one unified platform. You can use workflows for predictable steps, agents for more open-ended work, and combine both to automate business processes from end to end.

All makers can go to Copilot Studio and click “Try now” at the top of the homepage to start building capable agents with the streamlined building interface and modern orchestrator. The new experience and classic experience continue to coexist, so you can continue creating and managing your classic agents and workflows while you explore the new experience at your own pace.

We’re continuing to improve Copilot Studio as we learn. Share your thoughts using the feedback control in the top right corner of the product. Your input directly shapes what we build—and how you build—next.

Copilot Podcast Creations Stuck in “Creating” State

BrianHynes — Tue, 09 Jun 2026 02:51:38 GMT

My Copilot podcast creations are stuck in the “Creating” state and will not delete. The delete button is greyed out. I have already tried closing all browsers, restarting my iPad, phone, and PC, and the issue persists across all devices. It looks like the jobs are stuck in the backend queue and cannot be cleared from my side. I also attempted to open a support chat, but the service request auto‑closed before an agent joined.

Is there a way to clear these stuck podcast creations on the backend, or can someone from Microsoft confirm if this is a known issue?

Issues with using Copilot on Outlook Calendars

abayer — Mon, 08 Jun 2026 19:44:16 GMT

Seems that Copilot cannot decipher calendars very well. I have tried several times to automate some work on Outlook Calendars and Copilot is completely lost when it comes to working with calendars. One example was when I tried to move 3 attendees from meetings I had scheduled out for several months from required to optional. It told me it did not have meetings with these 3 people in attendance but showed me events with these 3 people in attendance and asked if I wanted to look at these events!!! Also one other recent instance was to take a Group Calendar and just list out the daily events for the next several months. It seems like it is unable to work with calendars in Groups?

File Uploads Not Passed to Custom Engine Agent in Microsoft 365 Copilot Chat

GullettBrian — Mon, 08 Jun 2026 15:56:12 GMT

Hi all,

I'm working with a custom agent built in Copilot Studio (full authoring experience — topics, knowledge sources, agent flows) published to both the Microsoft Teams channel and the Microsoft 365 channel.

I've noticed a significant UX discrepancy when it comes to file and image attachments, and I want to confirm my understanding and check whether any workaround or roadmap item exists.

What works:

✅ File/image uploads work as expected in the Copilot Studio test pane
✅ File/image uploads work in Teams chat when interacting with the agent

What doesn't work:

❌ File/image uploads do not reach the agent when interacting via the Microsoft 365 Copilot app (both the desktop app and the web experience at microsoft365.com)

The UX problem:

The M365 Copilot app presents a "+" button in the chat input area with options including "Upload" and "Take screenshot." Users naturally assume these options work. The file even appears as an attachment in the sent message — but the agent never receives it. There's no warning, error, or indication to the user that the attachment was silently dropped.

This creates a misleading experience, particularly for end users who have no visibility into the channel behavior differences.

What I've found so far:

I'm aware this is documented as a known issue for custom engine agents in the Microsoft 365 Copilot Extensibility Known Issues page:

"File attachments — Users can't upload files in agent chats and the agent can't return files for download."

I also found a related GitHub issue (OfficeDev/microsoft-365-agents-toolkit #15325) where a Microsoft team member confirmed this is a "Copilot platform shortage" — not an Agents Toolkit issue — with no published ETA.

My questions for the community and any Microsoft product team members:

Is there any currently supported workaround to enable file/image input for a Copilot Studio agent running in the M365 Copilot app (desktop or web)? For example, any manifest configuration, agent settings, or alternate approach?
Is this limitation being actively worked on? Is there a roadmap item or Microsoft 365 feature ID that can be tracked for when file attachment support is extended to custom engine agents in the M365 Copilot chat experience?
Is the UI behavior (showing upload options that don't work) being addressed separately? Even if full file processing isn't ready, a visible warning or disabled state in the UI would significantly reduce user confusion.

Any insight from others who have hit this — or from Microsoft PMs — is appreciated. Happy to share more configuration details if helpful.

Thanks!

Brian

Best Practices for Copilot Studio Environment Strategy and Application Lifecycle Management (ALM)

JohnNaguib — Mon, 08 Jun 2026 12:06:45 GMT

As organizations increasingly adopt Microsoft Copilot Studio to build intelligent copilots, virtual assistants, and AI-powered business solutions, establishing a robust environment strategy and Application Lifecycle Management (ALM) framework becomes critical. While creating copilots is relatively straightforward, managing them across development, testing, and production environments requires careful planning to ensure scalability, security, governance, and operational excellence.

Deleted Copilot Chats and Temporary Chat: What End Users Should Know

Teresa_Cyrus — Sun, 07 Jun 2026 17:23:02 GMT

I published a short video for end users who are asking a practical Copilot question:

Can employers see deleted Copilot chats?

The question usually starts when users see the “Permanently delete chat?” warning in Copilot.

That warning can be easy to misunderstand, especially in work or school accounts where workplace policies may still apply.

The video explains this in plain language, including:

What users should understand before deleting Copilot chats
Why Temporary Chat needs a closer look
Why deleted from your view may not mean the same thing in a workplace account
What users should avoid typing into Copilot at work

Watch the video here:

Copilot Studio Preview : MCP Agent works in Teams but not in Microsoft 365 Copilot Chat

CoralieSimonaire — Sun, 07 Jun 2026 05:45:06 GMT

I’m currently testing the new preview version of Copilot Studio and I ran into a behavior I’d like to validate with the community.

I created a custom Copilot agent using the new interface, connected to a Microsoft Learn MCP server (for retrieving official documentation), and deployed it across both:

- Microsoft Teams

- Microsoft 365 Copilot (Copilot Chat)

Configuration-wise, everything seems correctly set up:

- Agent published

- Channel enabled for Teams and Microsoft 365 Copilot

- Permissions and access configured

- MCP tool working properly

Here is the key point:

- In Microsoft Teams:

The agent works perfectly.

It correctly calls the MCP server, retrieves Microsoft Learn documentation, and returns accurate responses.

- In Microsoft 365 Copilot Chat:

The same agent does not work at all.

No MCP call is triggered, and no response is generated from the agent.

Instead, Copilot returns the following message:

"Sorry, I am not able to find a related topic. Can you rephrase and try again?"

Even with:

- Explicit invocation using @AgentName

- Very simple prompts

- Minimal instructions

- Added knowledge sources (for testing)

The behavior remains the same.

At this point, it looks like:

- The agent is accessible and deployed

- But it is not actually executed by the Microsoft 365 Copilot runtime

Has anyone experienced the same behavior with agents in the new Copilot Studio preview, especially when using MCP tools?

Is there any known limitation or requirement for agents to be properly executed inside Microsoft 365 Copilot Chat (compared to Teams)?

Thanks in advance for your feedback.

Can Microsoft Frontier Program Copilot Cowork Agent Delegate Tasks to Other Copilot Agents?

Farhan_akhtar — Fri, 05 Jun 2026 04:01:54 GMT

Hi everyone,

I'm currently exploring the capabilities of Copilot Cowork that is available through the Microsoft Frontier Program, and I'm trying to understand whether a multi-agent orchestration pattern is officially supported.

My Use Case

I want users to interact with only a single, central Copilot Cowork agent.

For example:

User asks the Cowork agent to create or update a Jira ticket.
Instead of Cowork handling the Jira operation directly, it delegates or hands off the task to a dedicated Jira Copilot Agent.
The Jira agent performs the required actions and returns the result.
The Cowork agent then presents the final response back to the user.

Similarly, I would like to have specialized agents for:

Jira
ServiceNow
Knowledge Management
HR Operations
Internal IT Support
Other business systems

The goal is to have Cowork act as an intelligent orchestrator/router while specialized agents handle domain-specific operations.

Questions

Is agent-to-agent delegation or handoff officially supported in Copilot Cowork (Frontier Program)?
Can Cowork directly invoke another Copilot Studio agent?
Is there any built-in multi-agent orchestration framework available today?
If this is supported, what is the recommended architecture and implementation process?
If it is not currently supported, what workarounds are people using?
- Power Automate?
- Agent as a tool/action?
- Custom APIs?
- Azure AI Foundry / Azure AI Agent Service?
- Other approaches?

I'm specifically looking for guidance from anyone who has worked with Copilot Cowork in the Frontier Program, since the documentation and public examples seem to focus mostly on standalone agents.

Any insights, architecture diagrams, documentation links, or real-world experiences would be greatly appreciated.

Thanks!

Designing Multi-Agent Systems in Copilot Studio

JohnNaguib — Thu, 04 Jun 2026 10:52:18 GMT

Modern organizations rarely solve complex business problems with a single AI assistant. Customer support, IT operations, sales, HR, and analytics teams all have different goals, data sources, and workflows. This is where multi-agent systems become valuable. Instead of relying on one large, general-purpose agent, a multi-agent architecture uses several specialized agents that collaborate to complete tasks efficiently.
