Microsoft Cowork (Frontier) Scheduled Runs Can't Access Custom Plugins/MCP Tools
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!Copilot and DLP policy behaviours
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.

Please help
The Windows App isn't viable at present
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.
Copilot Podcast Creations Stuck in “Creating” State
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?File Uploads Not Passed to Custom Engine Agent in Microsoft 365 Copilot Chat
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! BrianBest Practices for Copilot Studio Environment Strategy and Application Lifecycle Management (ALM)
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. https://dellenny.com/best-practices-for-copilot-studio-environment-strategy-and-application-lifecycle-management-alm/
Copilot Chat missing in Outlook Web and Outlook Classic
Hello, since recently we are experiencing a tenant wide issue with Microsoft Copilot Chat in Outlook. Environment: Microsoft 365 Business Premium Microsoft 365 Copilot Chat enabled Copilot Chat is pinned for all users via admin settings Copilot Chat works in other Microsoft 365 apps (e.g. Word) Copilot Chat is missing in Outlook Web (OWA) and Outlook Classic for all users in the tenant Key details: No recent admin, policy, or licensing changes were made Copilot Chat does not appear in OWA, which suggests a backend or service side issue The behavior is consistent for all users Questions: Is anyone else seeing Microsoft 365 Copilot Chat disappear from Outlook Web or Outlook Classic tenant wide? Has Microsoft changed the availability or scope of Copilot Chat in Outlook recently? Are there known dependencies or rollout changes that affect Copilot Chat visibility in Outlook specifically? Any confirmation from other tenants or additional technical insight would be helpful.Copilot Studio Preview : MCP Agent works in Teams but not in Microsoft 365 Copilot Chat
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.Deleted Copilot Chats and Temporary Chat: What End Users Should Know
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: https://youtu.be/ND9Cdp5h9rs?si=FyBkInRHpVgc_x1I Supporting article: https://traccreations4e.com/can-employers-see-deleted-copilot-chats/ Related deletion guide: https://traccreations4e.com/copilot-delete-chat-history/ traccreations4e-p26 6/8/2026Can Microsoft Frontier Program Copilot Cowork Agent Delegate Tasks to Other Copilot Agents?
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!Microsoft Introduces Scout: The Always-On Personal AI Agent
Microsoft has officially unveiled Microsoft Scout, a new AI-powered personal agent designed to work continuously in the background and help users manage tasks, schedules, communications, and workflows across the Microsoft 365 ecosystem. Announced on June 2, 2026, Scout represents Microsoft’s latest step toward autonomous AI agents that move beyond traditional chatbot interactions and actively help users get work done. https://dellenny.com/microsoft-introduces-scout-the-always-on-personal-ai-agent-that-could-redefine-workplace-productivity/Learning Agent by Microsoft: The Future of Personalized AI-Powered Employee Upskilling Has Arrived
In today’s rapidly evolving workplace, one challenge continues to stand out for organizations across industries: keeping employee skills aligned with changing business needs. Traditional training programs often struggle to deliver relevant learning experiences at the right time, leaving employees overwhelmed with generic courses that may not match their career goals or daily responsibilities. https://dellenny.com/learning-agent-by-microsoft-the-future-of-personalized-ai-powered-employee-upskilling-has-arrived/Copilot Studio Agent resetting when processing PDF drawings (300MB+) via Claude 4.6 Sonnet
Hello everyone, I am building an automated drawing review verification agent inside Copilot Studio using the Claude 4.6 Sonnet model. The goal of the agent is to read a comments package (20-40MB) and verify if those design comments were successfully incorporated into a milestone drawing set (300MB–400MB). When testing this workflow natively within Claude, the model handles the token load perfectly and returns an accurate compliance/incorporation summary within approximately 20 minutes. However, when running the exact same agent setup within Copilot Studio, the conversational canvas repeatedly crashes and resets the session. I suspect I am hitting the 100-second synchronous conversational timeout or overloading the chat runtime payload limits due to the massive file sizes. Because of corporate compliance policies, this agent must live within our Microsoft tenant so it can be scaled across our operations team via Microsoft 365. How can I fix Copilot Studio to have its performance match Claude's, as it is utilizing the same agent model. I am fairly new to working with AI but am willing explore any avenue as if I can figure out a solution this will help save a lot of time for colleagues. Thanks in advance for any insights!Designing Multi-Agent Systems in Copilot Studio
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. https://dellenny.com/designing-multi-agent-systems-in-copilot-studio/Copilot Studio Pricing Explained for Enterprises: Licensing, Costs, and ROI in 2026
As enterprises accelerate their AI adoption strategies, Microsoft Copilot Studio has emerged as one of the most powerful platforms for building custom AI assistants, automating business processes, and creating intelligent customer experiences. Whether you’re developing internal employee copilots, customer support agents, or workflow automation tools, Copilot Studio provides a flexible environment to create AI-powered solutions tailored to your business needs. https://dellenny.com/copilot-studio-pricing-explained-for-enterprises-licensing-costs-and-roi-in-2026/Copilot studio Agent Dataverse index issues.
We are testing a Copilot Studio agent and would like to test/use Dataverse as a data source. At a very basic level, the Dataverse table has been created with the following columns: Category Question and topic Answer to customer The challenge is that our Copilot Studio agent cannot find any relevant answers or data from our Dataverse table. Under ‘Knowledge’, our Dataverse table shows a status of: ‘Unknown’. It has remained in this state for several days. Removing and re-adding the knowledge source does not help. What are we doing wrong?
