co-pilot and other AI platforms are horrible
I spent more than three hours trying to solve a problem sharing calendars. Co-pilot spun me around in circles. I understand that Microsoft fired many programmers and depend more on co-pilot. This is a huge mistake. after all of the hours, I gave up and now I will have to pay a human to solve my computer problem. I sincerely hope that someone in Microsoft, who has a connection to decision making, will read this a take it seriously. I have used Microsoft hardware and software for more than 40 years, all the way back to Anytime, Anywhere Learning as a trainer and presenter. Could a human who is not interested in corporate profit pay attention to this huge problem.
Cowork tab appearing despite Admin settings
The Cowork tab in the Copilot App has started to appear for some of our Basic and Premium users. I'm not sure why this is happening as we have not setup any usage-based billing and explicitly disabled the following admin setting: Despite this, the users are able to click on the Cowork tab and enter a prompt. When it is submitted, Copilot tries to login, fails and continues trying to authenticate over and over again. I also cannot find the Copilot Cowork agent (1.3.0) in the Agent Registry to block it.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.Copilot Connectors >Azure DevOps Work Items >Add Property
Hi I have setup the Azure DevOps Work Item connector and all is working OOTB. However when I try to 'Add a new source Property' and add for example 'TargetDate' when I publish the schema change it errors with: Schema failed to publish with error [Removal existing property is not allowed.] I havent removed anything just added. Anyone else experienced this? Many thanksHas 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 risk
Prompt Lab: Three Critical Bugs That Make It Unusable as a Prompt Management Tool
Product: Microsoft 365 Copilot — Prompt Lab (accessed via ... button in Copilot Chat) Date: June 1, 2026 Environment: M365 Copilot, Web (Edge), Work IQ mode Bug #1: Empty State Crash Steps to reproduce: Open Prompt Lab via the ... button in Copilot Chat Ensure "Your saved prompts" contains zero prompts (either as a new user or by deleting all saved prompts) Observe the result Expected behavior: An empty state placeholder (e.g., "You haven't saved any prompts yet.") Actual behavior: The entire Prompt Lab panel throws a red error banner: "Something went wrong. Please close the dialog and try again later." The "Your saved prompts" category does not render at all. The panel only shows Microsoft's preset categories (Prompt topics, Agent prompts). Why this matters: An empty container is a valid state — it is literally every new user's initial state. A UI component should never crash because a list has zero items. This is a null/empty array handling failure that should have been caught by basic QA. Bug #2: Search Does Not Index User's Saved Prompts Steps to reproduce: Save a custom prompt with a distinctive title (e.g., "AI每日新闻") and body containing the keyword "AI" Open Prompt Lab Use the search box at the bottom to search for "AI" Expected behavior: Search results include the user's saved prompt alongside Microsoft's preset prompts. Actual behavior: Only Microsoft preset prompts matching "AI" are returned (e.g., "Stay on top of AI," "Prompt Compliance"). The user's own saved prompt — whose title and body both contain "AI" — does not appear in the results. Why this matters: The search box creates a false expectation that it searches all prompts. In reality, it only indexes Microsoft's template library. This means as a user accumulates more saved prompts, the only way to find one is manual scrolling. A search function that excludes user-created content is fundamentally broken by design. Bug #3: Saved Prompts Lost During Migration Context: The standalone Copilot Lab / Prompt Gallery app was retired on July 15, 2025, and its functionality was merged into the built-in Prompt Lab within Copilot Chat. What happened: All previously saved prompts from the old Copilot Lab app are gone. They do not appear in the new Prompt Lab's "Your saved prompts" section. There was no migration notice, no export tool for end users, and no recovery path. Why this matters: Users invested time curating and refining their prompt libraries. Silently dropping that data during a platform migration — without warning, backup, or migration tooling — is a breach of user trust. Summary These three issues compound into a single conclusion: Prompt Lab is currently non-functional as a prompt management tool. Capability Status Reliable storage ❌ Data lost during migration Empty state handling ❌ Crashes when empty Search / retrieval ❌ Does not index user content Displaying Microsoft templates ✅ Works The only feature that works correctly is showcasing Microsoft's own preset prompts. For a tool whose entire purpose is to help users save, organize, and reuse their own prompts, this is an unacceptable state of quality. I'd strongly recommend the team prioritize: (1) proper null-state handling, (2) including user prompts in the search index, and (3) investigating whether migrated prompt data can be recovered from Substrate.Copilot Down - June 1st
I used Copilot this morning and everything was working smoothly. All of a sudden when I open the app on Windows I get this message "Couldn't load the app. Wait a bit, then try again." I tried using the version on Edge but I get a "503 Service Unavailable Error." I tried restarting my laptop and I get the same error. Checked on my phone app and indeed, it confirmed the service is down. Does anyone know when this will be resolved?Four open source projects to explore at Microsoft Build
Open source is where developers experiment, collaborate, and turn new ideas into tools that others can build on. At Microsoft Build, we’re creating a dedicated space for that energy: the Open Source Zone. This year, the Open Source Zone will bring together maintainers, contributors, and developers working on some of the most interesting open source projects in AI. Whether you’re building agents, experimenting with local models, exploring prompt workflows, or looking for practical ways to bring AI into your development process, this is a place to meet the people behind the projects and see what they’re building. The Open Source Zone is inspired by similar community spaces we’ve hosted at GitHub Universe: hands-on, conversation-driven, and centered on the people and projects moving open source forward. Meet the projects OpenClaw OpenClaw, originally Clawbot, formerly Clawdbot and briefly Moltbot,before landing on its current name (because naming is hard), is a personal AI assistant project built for developers who want more control over how AI agents run across tools, devices, and workflows. Its repository describes it as “your own personal AI assistant” across operating systems and platforms, with support for agent workspaces, skills, and device nodes. It has also become one of the fastest-growing open source projects on GitHub, with over 370,000 stars to date. At the Open Source Zone, attendees can learn how OpenClaw approaches personal agents, extensibility, and local-first experimentation. AutoGPT AutoGPT is one of the best-known open source projects in the autonomous agent space. The project’s mission is to make AI accessible for everyone to use and build on, with tools for building, testing, and delegating work to agents. Visit AutoGPT in the Open Source Zone to learn how the project is evolving agent development, benchmarking, frontend experiences, and practical workflows for building agent-powered applications. Come for the autonomous agents; stay for the very human maintainers. AutoGPT is also a member of GitHub’s Secure Open Source Fund, with a goal of enhancing AI security across the open source ecosystem. Open WebUI Open WebUI is a self-hosted, extensible AI platform for working with large language models. The project supports Ollama and OpenAI-compatible APIs and includes built-in RAG capabilities, making it a strong option for developers and organizations exploring local, private, or provider-flexible AI experiences. At Build, the Open WebUI team will show how developers can run, customize, and extend AI interfaces for their own environments. prompts.chat prompts.chat, formerly Awesome ChatGPT Prompts, is a curated collection of prompt examples for AI chat models. The project is designed to help people discover, share, and build better prompts for modern AI assistants. Created by Fatih Kadir Akın, a GitHub Star from Istanbul, prompts.chat reflects his work at the intersection of open source, developer education, and AI-assisted development.

Location of custom skills - cannot find them in OneDrive
I'm using Copilot Cowork to create skills, and Cowork insists the skills are being saved in OneDrive>Documents>Cowork>skills but I cannot find them in there. I cannot find the raw MD files anywhere in OneDrive, and Cowork can only surface them when I ask to see them. Anyone else experienced this and have the answer? I need to be able to create Cowork Skills and store them in a central repository for the team to use. #cowork
