Archivos bloqueados por Copilot al usarlos como fuentes en OneDrive personal
Hola comunidad, Quisiera compartir un problema que he estado enfrentando al trabajar con Copilot y documentos almacenados en mi OneDrive personal. Al intentar usar ciertos archivos como fuentes para proyectos, Copilot muestra el mensaje “The document is blocked by its content”, impidiendo que el archivo sea procesado. Los documentos afectados incluyen: Proyecto Educativo Institucional (PEI) Reglamento Interno Escolar Plan Anual de Gestión Otros documentos PDF y Excel con contenido normativo o institucional Aunque los archivos fueron creados por mí como persona natural y están en OneDrive personal, Copilot los clasifica como contenido altamente sensible, probablemente debido a: Lenguaje normativo o jurídico Estructura de reglamentos y protocolos Información institucional o disciplinaria Palabras clave asociadas a documentación oficial Formatos PDF/Excel con tablas, artículos o indicadores Entiendo que Copilot aplica filtros de seguridad para evitar procesar documentos que puedan contener información crítica o normativa, pero en este caso se trata de archivos destinados a publicación pública en la web de la escuela. Me gustaría saber: Si existe una forma de marcar estos documentos como seguros desde OneDrive personal. Si hay configuraciones específicas que permitan a Copilot procesar documentos normativos creados por el usuario. Si otros usuarios han enfrentado este tipo de bloqueo con contenido institucional no confidencial. Agradezco cualquier orientación o experiencia que puedan compartir. Saludos, Alex📣 Microsoft Copilot Studio and Agent Roadmaps Have a New Home

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! Brian
You don't have access to talk to this bot, contact the owner. copilot studio
I created a copilot studio agent and then embedded it inside a code app. It works fine but i am facing the below error. You don't have access to talk to this bot, contact the owner. copilot studio I have provided Microsoft based authentication and am an owner so will have access to the bot. Yet facing the above issue. Is there something i am missingCopilot Studio + SharePoint: Markdown (.md) Files in Doc Libraries Supported as Knowledge Sources?
Hi all, We’ve been doing some deeper testing with Copilot Studio agents grounded in SharePoint knowledge sources, and I’m hoping to clarify whether what we’re seeing is a known limitation or an undocumented gap. Scenario A Copilot Studio agent uses SharePoint document libraries as a knowledge source The library contains Markdown (.md) files that are intentionally used as canonical design references The same .md files: ✅ Work well when uploaded directly to the agent ❌ Are not retrievable or citable when stored in a SharePoint library and added as a SharePoint knowledge source To help with grounding, we created modern SharePoint index pages that: Explain what the markdown collections are (Patterns, ADRs, Guardrails) Link directly to the canonical folders and files Explicitly state that the .md files are the source of truth The agent can: Discover and summarize the index pages correctly Understand that .md artifacts exist and where they live But it cannot: Read the content of the individual .md files Apply a specific pattern or ADR from those files in a design conversation Cite them as sources, even when permissions and search indexing are confirmed What We’ve Checked Permissions (agent user has access) Folder depth (kept shallow) Search results (markdown files appear in SharePoint search) SharePoint indexing status Work IQ enabled Same content works when attached directly to the agent This behavior also seems consistent with what others have reported here: Markdown works when uploaded directly Markdown retrieval degrades when hosted in SharePoint libraries Questions for the Product Team / Community Are Markdown (.md) files in SharePoint document libraries officially supported as Copilot Studio knowledge sources today? If yes, are there specific constraints (file size, rendering, parsing, indexing) that differ from Word/PDF? If no (or “not yet”), is this a known limitation on the roadmap? Is the recommended pattern to: Convert important markdown files into .aspx pages, or Use thin “index / summary” pages and keep markdown canonical until retrieval improves? We’re happy to adapt our information architecture — just trying to align with the intended platform direction rather than work against it. Thanks in advance for any guidance or clarification. This capability is extremely powerful, and clearer expectations here would help a lot of teams make the right design tradeoffs.
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.

I’m seeing a persistent issue when integrating SharePoint lists with Copilot Studio agents. Any SharePoint list I add to an agent results in an error being shown in the Copilot Studio UI, but no error message, diagnostic detail, or failure reason is surfaced. I’ve removed and re-added the list connections multiple times and reproduced the issue across multiple agents, with the same outcome each time. Has anyone encountered this behaviour, or are there known issues or prerequisites (e.g. permissions, connector state, tenant configuration, or recent service changes) that could cause silent failures when integrating SharePoint lists?
