Publishing and Sharing Your Agent Across Microsoft Teams: A Complete Step-by-Step Guide
Microsoft Teams has become much more than a communication platform. It is now a central workspace where employees collaborate, manage projects, automate tasks, and interact with AI-powered assistants. With Microsoft Copilot Studio, organizations can build intelligent agents that answer questions, automate repetitive work, and improve productivity across departments. https://dellenny.com/publishing-and-sharing-your-agent-across-microsoft-teams-a-complete-step-by-step-guide/
Has anyone seen Excel workbooks become corrupt after using M365 Copilot to summarize data?
We’ve run into an issue twice where a user opened an existing Excel sales workbook, used Microsoft 365 Copilot in Excel to summarize/analyze the data, received the response successfully, and then later could no longer open the original workbook because Excel reported it as corrupt. Internally, this has been reported as happening on some files but not all, and it has occurred twice so far. I’m trying to determine whether this is: a known issue with Copilot in Excel a workbook-specific problem related to file location/sync/versioning or something tied to workbook structure I did find public reports of related Excel Copilot issues — including Copilot crashing in Excel, failures that seem specific to certain workbooks, and Copilot-created Excel files being reported as invalid/corrupt — but I have not yet found a clear Microsoft-hosted thread describing this exact scenario with the original existing workbook becoming corrupt after summarization. If anyone has seen this, I’d appreciate any insight on: whether Microsoft has acknowledged a known issue whether this points to specific workbook features/structures whether there are logs or diagnostics that help isolate root cause whether there are best practices to reduce the riskTesting and Debugging Your Microsoft 365 Agent: A Complete Guide for Building Reliable AI Assistants
Artificial intelligence is transforming the way businesses work, and Microsoft 365 Agents are leading this change. These intelligent assistants can automate repetitive tasks, answer employee questions, summarize meetings, retrieve documents, and improve collaboration across Microsoft 365 applications. However, creating an agent is only the first step. The real challenge begins when it’s time to test and debug it. https://dellenny.com/testing-and-debugging-your-microsoft-365-agent-a-complete-guide-for-building-reliable-ai-assistants/Copilot Feedback - Power User Experience Improvements
As a frequent Copilot user for technical discussions, architecture, governance, Microsoft 365, Power Platform, and problem-solving activities, I would like more control over the user experience. Copilot has become a daily productivity tool, but several UI and usability improvements would significantly benefit advanced users. 1. Allow Disabling Suggested Follow-Up Prompts The suggested replies shown below every response may be useful for new users, but for experienced users they often add little value and consume screen space. Please provide an option to: Disable suggested prompts entirely Adjust their frequency or aggressiveness Enable them only for new conversations or learning scenarios 2. Make '/' and '@' Shortcuts Configurable The automatic triggering of slash commands and @ mentions while typing can be disruptive and may interrupt or replace text unexpectedly. Please allow users to: Disable these shortcuts Configure alternative trigger characters Require a keyboard shortcut before activating them 3. Add a Power User Mode Consider introducing a dedicated Power User Mode featuring: No suggested prompts Reduced UI clutter Compact layouts Fewer interruptions while typing Advanced customization options A productivity-focused experience 4. Compact Conversation View Long technical conversations can become difficult to navigate due to excessive spacing and scrolling. Please provide: A compact view option Reduced vertical whitespace More conversation content visible on screen 5. Conversation Search Many conversations contain valuable information that users want to revisit later. Please add the ability to: Search within a conversation Search code snippets and formulas Search by date or topic Quickly jump to matching results 6. Pin Important Messages Allow users to pin key answers, code snippets, formulas, decisions, or reference messages within a conversation so they can be easily found later. 7. Enhanced Copy Experience For technical users working with Power Apps, Power Automate, SQL, PowerShell, and other technologies: One-click copy for all code and formulas Preserve formatting during copy operations Support copying multiple related blocks together 8. User-Defined Response Profiles Allow users to create and switch between response styles such as: Technical Troubleshooting Power User Learning Mode Executive Summary Architecture Review This would reduce the need to repeatedly explain personal preferences. 9. Memory Transparency and Management Allow users to: View all stored memories and preferences Edit or delete individual memory items Temporarily disable specific memories Understand which memories are influencing responses This would improve transparency and trust. Summary Copilot is evolving from a simple chat tool into a professional productivity platform. Providing greater control over the interface, shortcuts, suggestions, memory, and conversation management would allow experienced users to tailor the experience to their workflow while preserving the current experience for those who prefer more guidance. Thank you for considering these improvements.
Microsoft's Copilot: A Frustrating Flop in AI-Powered Productivity
Microsoft's Copilot was supposed to be the game-changer in productivity, but it's quickly proving to be a massive disappointment. The idea was simple: integrate AI directly into Word, Excel, PowerPoint, and other Office tools to make our lives easier. But when it comes to actually performing specific functions, Copilot falls flat. Here’s the problem: when you ask Copilot to alter a document, modify an Excel file, or adjust a PowerPoint presentation, it’s practically useless. Instead of performing the tasks as requested, it often leaves you hanging with vague suggestions or instructions. Users don't want to be told how to perform a task—they want it done. This is what an AI assistant should do: execute commands efficiently, not just offer advice. What makes this even more frustrating is that other AI tools, like ChatGPT, can handle these tasks effortlessly. When you ask ChatGPT to perform a specific function, it does so without hesitation. It’s able to understand the request and deliver exactly what’s needed. But Copilot? It struggles with the basics, and that’s unacceptable, especially from a company like Microsoft. It’s frankly embarrassing that Microsoft can’t get this right. The whole point of integrating AI into these tools was to streamline workflows and boost productivity. But if Copilot can’t even manage simple tasks like formatting a document or adjusting a spreadsheet, then what’s the point? Users don’t need another tool that tells them how to do something—they need one that does it for them. Microsoft, you’ve missed the mark with Copilot. It's not just a minor inconvenience; it's a serious flaw that undermines the value of your Office suite. When other AI tools can easily accomplish what Copilot can't, it's time to reevaluate. Users expect more, and frankly, they deserve more for their investment. What’s been your experience with Copilot? Is anyone else finding it as frustrating as I am? Let’s talk about it.
Has model selection been removed from Microsoft 365 Copilot?
I noticed that the option to manually select GPT models in Microsoft 365 Copilot seems to be gone, or at least no longer visible. I have also seen similar concerns discussed on Reddit. Could Microsoft clarify the current status? - Has manual model selection been removed? - How can users know which model Copilot is currently using? - Is Copilot still using stronger models such as GPT-5.5, or only automatic routing now? - Why does “Deep Analysis” / “Think Deeper” appear to switch back to Auto mode? For corporate use, this lack of transparency is concerning. If I cannot see or control which model is being used, it reduces trust in the quality of the output and makes me more cautious about what tasks I rely on Copilot for. A clear statement from Microsoft would be appreciated.
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.

Let's start a new chat."
Hi All, We're currently using Copilot for Microsoft 365 in our business and I'm finding it incredibly annoying when Copilot tells me this. "Sorry, this conversation has reached its limit. Let's start a new chat." When I asked Copilot why, this is what I receive. "The message “Sorry, this conversation has reached its limit. Let’s start a new chat.” means that the current conversation has reached the maximum number of turns or messages allowed. Each conversation with me, Copilot Pro, has a limit on the number of turns it can take. Once this limit is reached, the conversation cannot continue further in the same thread. Starting a new chat will initiate a new conversation where you can continue to ask questions or request assistance. This is a measure to ensure optimal performance and user experience. I hope this clarifies your query! 😊" When I asked Copilot what the limit is, this is what I receive. "I’m sorry, but I can’t provide the exact number of turns or messages allowed in a conversation. The limit is set to ensure optimal performance and user experience. However, once the limit is reached, you can always start a new conversation. Please let me know if there’s anything else I can assist you with! 😊" I'd love to understand the logic for such a limitation. Can anyone kindly explain this is plain simple English please? Thanks!

Hello Community! Over the past few months, I've noticed that when using Copilot in Excel, the newest features appear in Excel on Web for weeks or months (also PowerPoint, and possibly Word and other M365 Applications) before appearing in Excel on Desktop App. Right now, this is occurring with Plan mode appearing in Excel Web although not Excel Desktop. Does anyone know why this occurs?What Is Microsoft 365 Agent Builder? A Beginner’s Guide
Artificial intelligence is changing how people work, communicate, and solve problems. Over the past few years, Microsoft has introduced several AI-powered tools to make everyday business tasks easier and more efficient. One of the newest additions to this growing ecosystem is Microsoft 365 Agent Builder, a feature designed to help users create intelligent AI agents without requiring advanced programming skills. https://dellenny.com/what-is-microsoft-365-agent-builder-a-beginners-guide/Scaling AI Agents with Kubernetes and Distributed Systems
Artificial intelligence has moved far beyond simple chatbots and rule-based automation. Today’s AI agents can reason through complex problems, interact with multiple tools, collaborate with other agents, and perform tasks with minimal human intervention. As organizations deploy AI agents across customer service, software development, research, finance, healthcare, and operations, one challenge becomes impossible to ignore: how do you scale AI agents reliably? https://dellenny.com/scaling-ai-agents-with-kubernetes-and-distributed-systems/
Custom Agent Builder agent suddenly failing with "Oops, something happened" - no config changes
Hi All, We built a custom agent in Agent Builder (Microsoft 365 Copilot) that generates a Word risk assessment by grounding on a contract (either the document currently open via the Word Copilot add-in, or a file uploaded in the web browser chat), plus a fixed set of knowledge sources (guidance notes, playbooks). It worked reliably for about 5 days while I was testing it solo. We then rolled it out to appr. 20 users, and shortly after, it started failing consistently with a generic "Oops, something happened, try again" error, typically after a long delay, in both the Word add-in and the browser version. I can't confirm causation, but the timing lines up closely with when we expanded from single-user testing to ~20 concurrent users. I don't know whether this points to a tenant-level capacity/concurrency limit being hit, or its something else, just stating it in case others have seen a similar threshold effect. Is this a known concurrency/capacity limit for Agent Builder agents once usage scales up, or a separate backend regression affecting document grounding, and has anyone else seen this pattern after moving from single-user testing to broader rollout?The Sadly Unfulfilled Promise of the Outlook Calendar Agent
The Outlook calendar agent seemed to be the answer to the difficulties that I sometimes encounter when trying to sort out my schedule. Alas, the agent failed to deliver when it was given guidelines about how I wanted to create appointments. The overall experience makes me consider whether the huge investment Microsoft is making to infuse AI into its products sometimes turns out duds. Like an agent that can’t schedule. https://office365itpros.com/2026/07/07/calendar-agent-disappoints/Two Microsoft 365 Copilot Changes That Just Make Sense
Two recent changes to the Microsoft 365 Copilot Chat app have made the app easier to use. Interaction persistence is better, meaning that chat threads are always created and available to go back to if necessary, and Copilot memory is managed more easily. Copilot memory is an intensely personal capability. If you spend the time to figure out the instructions that Copilot should always remember, the quality of Copilot responses will be much better. https://office365itpros.com/2026/06/29/copilot-memory-updates/Cowork tasks not accessible - where are my cowork results?
I've been using cowork for several tasks/sessions, and I was impressed. When I was using it, I could switch between tasks/sessions and had always access to the results. Documents, and conversation. I even could continue and improve results a week later. Now, when I go to the cowork section in copilot, I still can see the list of cowork tasks at the left side. But each of them is completely empty. I mean white space, nada, nothing there.. not even a textbox to enter something. I tried with the M365 App, Edge, Firefox, new design. old design.. nada. So, what happened to my conversations and the generated documents? Is it a bug or expected behaviour? If it's expected, cowork is becoming less interesting for me. It means that I have to save my work/cowork all the time manually outside of the conversation (which I did for most of the generated documents, but not all) Help--- can I get the conversations and documents of each cowork session back, please?

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! BrianHas Anyone Successfully Used the Fabric Data Agent Connector with Copilot Agent?
Hi everyone, I'm facing an issue with a published Copilot agent in the Microsoft 365 app channel. The agent is configured with the Fabric Data Agent connector along with documentation as knowledge sources. However, while the agent works as expected with the Power BI connector, it fails to return responses when using the Fabric Data Agent connector in the Microsoft 365 app I understand the Fabric Data Agent connector is still in preview, but I wanted to check: Has anyone successfully used the Fabric Data Agent connector with a Copilot agent in the Microsoft 365 Copilot app? Is this a current limitation of the Microsoft 365 app channel or the preview connector? Are there any known workarounds? Is there any estimated timeline for the Fabric Data Agent connector to reach General Availability (GA) and support the Microsoft 365 app channel I'd appreciate any insights or experiences from others who have tested this scenerio Thanks!
