missing co-pilot conversation history after update:
I have updated Co-pilot this morning. when co-pilot restarted my chat history/ conversations were uploaded... except for one. the affected conversation started in January 2026 and is significantly larger than your other chats (a project based sparring exchange). I refreshed, but that did not work out: error message ("Unable to load"/white screen. other smaller conversation did up-load correct. I use Copilot app version macOS Tahoe 26.6.2 version. support could not help me and send me to this platform....
Can Copilot help write better performance review comments?
We just finished our mid-year review cycle and the feedback quality from managers was honestly terrible. Lots of gems like "100%" or “Fully agree“. Someone on my team suggested using Copilot to help managers draft better feedback but I'm not sure how that would work practically. Like where would the AI even pull context from?Introducing Microsoft Copilot Cowork
For the last couple of years, generative AI has mostly acted like an eager, highly capable research assistant. You give it a prompt, it spits out an email draft, a summary, or a bit of code, and then it waits for you to tell it what to do next. It’s useful, but the operational drag of constantly guiding it step-by-step still falls squarely on your shoulders. That dynamic is officially changing. With the general availability of Microsoft Copilot Cowork, Microsoft is shifting AI from a passive conversational tool into an autonomous execution agent. Instead of prompting an AI to help you build a deck, you can now delegate entire multi-step workflows to Cowork, let it run in the cloud background, and simply review its work at key checkpoints. Here is a breakdown of what Cowork is, how it functions, and why it changes standard team workflows. What is Microsoft Cowork? At its core, Cowork is an automation and execution layer built directly into Microsoft 365. Rather than responding to single prompts, Cowork translates a high-level intent into a multi step project plan, coordinates across multiple M365 apps simultaneously, and delivers a completed result. The technology behind it stems from Microsoft’s partnership with Anthropic, effectively integrating cloud based agentic workflows under your organization's existing enterprise security, compliance, and identity controls. Driven by an organizational context engine called Work IQ, Cowork doesn't just look at a single file, it synthesizes signals across your Outlook emails, Teams chats, SharePoint documents, and calendars to understand how your team operates. How It Works: From Intent to Action Using Cowork feels fundamentally different from standard prompting. You can input an outcome request using natural language (up to 16,000 characters) and attach relevant background files. The Execution Process Deconstructs the Goal: Cowork breaks your request down into an operational roadmap. Background Execution: The agent executes the plan in a protected cloud sandbox. You can close your laptop or switch devices, and the task keeps running. Human-in-the-Loop Approvals: For medium-to-high-risk actions—like firing off a client email or posting a final update to a public Teams channel Cowork pauses and explicitly asks for your permission via a risk level indicator card. The Power of Reusable "Skills" What makes Cowork a true team framework is its underlying Skills architecture. Out of the box, Cowork ships with 13 built-in skills spanning core workplace needs: Skill Group Core Capabilities Content & Files Create and edit Word documents, Excel sheets, PowerPoint presentations, and PDFs. Organization Automated calendar optimization, meeting intelligence, scheduling, and custom daily briefings. Communication Multi-app drafting across Email, Teams channels, and structured Adaptive Cards. Analysis Deep Research capabilities that aggregate broadly across multiple corporate sources. Building Custom Workflows Beyond the defaults, teams can create up to 20 custom skills by simply dropping a formatted markdown file (SKILL.md) into a designated OneDrive folder. Instead of every employee reinventing how they handle a project handover, a weekly status update, or client onboarding, the team can standardize a repeatable workflow. For example, a custom "Weekly Reporting" skill can instruct Cowork to scan team updates, flag blockers, cross-reference an Excel sheet, and format a client-ready summary automatically every Friday morning. Managing the Sandbox: Cost and Controls Because Cowork handles complex, long-running tasks that call multiple models, its runtime is consumption-based rather than a flat monthly fee, tracking via Copilot Credits. Tasks are categorized based on their complexity: Light/Medium Tasks: Applying structured reasoning across a few local sources to generate dual outputs. Heavy Tasks: Deep reasoning that aggregates data across a massive corporate ecosystem and outputs multiple complex documents. To prevent budget overruns, IT administrators have granular control over the ecosystem. Admins can set tenant, group, and user-level spending limits, and users can request additional credits directly from the Cowork interface when tackling particularly heavy computational tasks. Sum up Microsoft Cowork marks a distinct evolution in workplace productivity. The value isn't just about writing a single email faster; it's about reducing the daily operational chaos by automating the manual coordination that slows teams down. By handing off predictable rules-based workflows to an autonomous digital teammate, professionals can shift their energy away from administrative legwork and focus it back onto strategic decision-making.
Copilot Notebook - No web search enabled
HI, It appears this just isn't a function of Notebook currently, and the only other post I see about it was from last year where someone couldn't get it to work. Does anyone know if this is a planned change to add it in the future? I'm not seeing the usefulness of Notebooks if it can only search internally. My SharePoint can do that without an extra step. If it has since been added since last seen, does anyone know where the settings are for it so I can have our admins look? Our regular Copilot Work chats do allow web searches, so it's not that.Web Search in Copilot Notebooks Still Disabled Despite Policy Configuration
I've followed Microsoft's documentation to enable Web Search in Microsoft 365 Copilot Notebooks by creating a policy in the Cloud Policy Service. The policy includes: Allow web search in Copilot Pin Microsoft 365 Copilot Chat Allow creation and viewing of Copilot Pages and Notebooks The policy is assigned to an All Staff group, and users have the appropriate Microsoft 365 Copilot licenses. It's been over 24 hours since the policy was applied, but the Web Search toggle in Copilot Notebooks is still greyed out. I've verified: Users are on the Current Channel for Microsoft 365 Apps No conflicting Intune or GPO settings Network access to Bing and Microsoft services is unrestricted Relevant Microsoft documentation: Manage public web access in Microsoft 365 Copilot: https://learn.microsoft.com/en-us/copilot/microsoft-365/manage-public-web-access Configure policies using the Cloud Policy service: https://learn.microsoft.com/en-us/deployoffice/admincenter/overview-cloud-policy Microsoft 365 Copilot service description: https://learn.microsoft.com/en-us/microsoft-365-copilot/microsoft-365-copilot-service-description Has anyone else run into this issue? Any ideas or workarounds?
Copilot in Word can't read chat attachments; Word for web file picker shows “no token obtained”
Summary of the issue I am seeing a persistent failure with Copilot attachments specifically inside Microsoft Word. Copilot in Word desktop and Word for the web can recognize an uploaded chat attachment by filename or OneDrive URL, but it cannot read the file contents. It reports the uploaded file as empty, corrupted, or in a format it cannot process. The same files are successfully read by standalone Microsoft 365 Copilot Chat using the same Microsoft account, and file uploads also work in Excel Copilot and PowerPoint Copilot. Failure started 10 days ago, with no obvious changes in settings on my end. The most useful diagnostic clue so far is that Word for the web’s Copilot attachment/file-picker path has also failed before any file was selected, showing “Something went wrong, please try again or refresh the page, no token obtained.” In Chrome, Word for the web produced a SharePoint-style error page with a correlation ID. This makes the issue look less like a bad file or local Word installation problem and more like a Word Copilot attachment-picker, OneDrive/SharePoint authorization-token, or file-handoff problem. Environment and scope Windows 11, Pro. Microsoft Word desktop: issue reproduced after updating Office and Windows. Word for the web: issue reproduced in Edge, Edge InPrivate, and Chrome. Standalone Microsoft 365 Copilot Chat / copilot.microsoft.com / m365.cloud.microsoft/chat: uploaded files can be read successfully with the same Microsoft account. Excel Copilot and PowerPoint Copilot: uploaded files work. OneDrive in Chrome: upload/download and file access work normally with the same account. Same Microsoft account used throughout. File types tested include tiny TXT files, PDFs, and DOCX files, including a complex DOCX. Copilot in Word can read the active Word document normally; the failure is limited to files uploaded as Copilot chat attachments inside Word. Observed behavior In Word desktop, Copilot chat accepts or recognizes the attachment metadata, including filename and sometimes a OneDrive URL, but when asked to read or summarize the file it says the file appears to be empty, corrupted, or in a format it cannot process. This happens even with a very small TXT test file. In Word for the web, the same general failure occurs. In one clean test, I created a brand-new blank Word document in Word for the web, opened Copilot, attached a tiny TXT file, and asked what the uploaded TXT file said. Copilot responded: “The uploaded file ingestion_test_731_1915.txt appears to be empty, corrupted, or in a format I can’t process, so I can’t read any text from it.” In another Word for the web test, clicking Copilot’s “+” attachment button and choosing either “My Files” or “Recent” opened a mostly blank window saying: “Something went wrong, please try again or refresh the page, no token obtained.” This occurred before any file was selected. In Chrome, Word for the web produced this error when trying to use the Copilot attachment flow: “Sorry, something went wrong. An unexpected error has occurred. Technical Details: Troubleshoot issues with Microsoft SharePoint Foundation.” The error included Correlation ID 64062ea2-3083-8000-a0f7-fbf4f6bb617d and Date/Time 8/4/2026 12:21:38 PM. Evidence matrix Test Result Standalone Microsoft 365 Copilot Chat / copilot.microsoft.com DOCX, PDF, and TXT uploads can be read successfully with the same account. OneDrive in Chrome Upload, download, and file access work normally. Excel Copilot Uploaded files work. PowerPoint Copilot Uploaded files work. Word desktop Copilot Attachments are recognized but reported as empty, corrupted, or unprocessable. Word for the web in Edge/InPrivate Tiny TXT attachment reported as empty, corrupted, or unprocessable. Word for the web attachment picker “No token obtained” message before file selection. Word for the web in Chrome SharePoint Foundation-style error with correlation ID 64062ea2-3083-8000-a0f7-fbf4f6bb617d. Word Copilot reading the active document Works normally. Troubleshooting already tried Updated Microsoft Office / Microsoft 365 desktop apps. Updated Windows. Restarted Word multiple times. Restarted the computer multiple times. Signed out and signed back in. Confirmed that the same Microsoft account is being used; there is only one Microsoft account involved. Toggled connected experiences off and back on, including restarts between changes. Started Word in Safe Mode. In Safe Mode, Copilot chat opened but did not activate properly; the Copilot pane appeared to cycle in the background and sub-windows were blank/unusable. Tested with a brand-new blank Word document in Word for the web. Tested in Edge, Edge InPrivate, and Chrome. Tested with very small TXT files as well as PDF and DOCX files. Confirmed OneDrive itself works normally in Chrome by uploading and accessing files successfully. Confirmed standalone Copilot and Excel/PowerPoint Copilot can process uploaded files successfully. Why this does not look like a local file or browser problem The same uploaded files work in standalone Microsoft 365 Copilot Chat, and OneDrive upload/download works normally. The issue also reproduces across Word desktop and Word for the web, across multiple browsers, and with a brand-new blank Word document. Because Word Copilot can read the active document but cannot acquire or process uploaded chat attachments, the failure appears isolated to the Word-integrated Copilot attachment picker, authorization-token acquisition, or OneDrive/SharePoint file-handoff path. Most likely failure area My current working theory is that Word-integrated Copilot is failing to obtain or pass the required SharePoint/OneDrive authorization token for Copilot chat attachments. The “no token obtained” message and the SharePoint Foundation correlation ID point toward the file-picker or backend handoff path rather than file contents. It may be account-specific, feature-flight/routing-specific, or a Microsoft-side regression affecting Word Copilot attachment handling. Request for help Has anyone seen Word Copilot attachments fail in this way while standalone Copilot, OneDrive, Excel Copilot, and PowerPoint Copilot all still work? Are there known Word Copilot attachment-picker, OneDrive/SharePoint token, or feature-routing issues that can affect only Word-integrated Copilot? If Microsoft support or engineering can trace backend logs, the most relevant correlation ID I have is 64062ea2-3083-8000-a0f7-fbf4f6bb617d from 8/4/2026 at 12:21:38 PM in Word for the web in Chrome. I would especially appreciate suggestions for anything beyond the standard local troubleshooting already tried. At this point, the pattern suggests the next useful step is probably backend investigation of the Word Copilot attachment/file-picker authorization flow rather than more file-format testing or local repair.Copilot Projects folder empty after failed upgrade - case #7108610754
Hi, I'm following up on Microsoft Support case #7108610754. My Copilot Projects folder is completely empty (shows "No projects yet" on the Projects page), and several project folders with their full chat histories that existed before are no longer visible. The support chat marked the case as "resolved" and closed it, but nothing was actually restored - the folder is still empty. Could the Copilot product team please investigate this server-side? Happy to share the case number and account details privately if needed. Thank you.
Disabling Agent Creation for End Users with Copilot for Microsoft 365
Hello! I am an IT admin at my organization, and we recently rolled out Copilot for Microsoft 365 for all end users. I would like our end users to be able to access agents published by my organization and Microsoft (Analyst, Researcher, etc.) but I do not want them to be able to create agents in Copilot Studio OR Agent Builder. We have disabled Copilot Studio at the license level, but our end users are still able to create agents in the M365 Copilot app with the "New Agent" button. To summarize, I want our users to be able to access Agents created by our organization and Microsoft, but I do not want them to be able to create any agents of their own at this time. Is there a way to do this? Thank you in advance, stevenwagner
How to fix the missing Copilot integration in Outlook?
