Copilot in OneNote cannot access content in sidebar (Microsoft 365 Premium)
a { text-decoration: none; color: #464feb; } tr th, tr td { border: 1px solid #e6e6e6; } tr th { background-color: #f5f5f5; } Hello everyone, I'm hoping someone from the OneNote or Copilot team can help with an issue that has prevented me from using Copilot in OneNote for approximately two months despite having an active Microsoft 365 Premium subscription. Issue Copilot can detect that a OneNote page is open, but it cannot access or read the contents of the page. For example, if I open a page named 1Cor4:1-16.onepart or create a brand-new test page, Copilot acknowledges that the page exists but responds with something similar to: "I can see that the file is open, but I cannot access the note contents." As a result, Copilot cannot summarize, analyze, answer questions about, or otherwise interact with the contents of the current page. Environment Microsoft 365 Premium (Personal Subscription) OneNote for Microsoft 365 Version 2608 Build 16.0.20326.20100 (64-bit) Windows Desktop Notebooks stored in and synced through OneDrive Troubleshooting Completed I have already performed extensive troubleshooting, including: Verifying my Microsoft 365 Premium subscription is active Verifying I am signed into the correct Microsoft account Signing out and back into Office and OneNote Confirming notebooks are syncing properly Updating Office and OneNote to the latest version Restarting OneNote and Windows multiple times Creating brand-new notebooks and test pages Testing across multiple days and sessions The issue is fully reproducible on both existing notebooks and newly created notebooks. Microsoft Support Findings I have already worked directly with Microsoft Support. A support technician remotely connected to my computer and reviewed my configuration. They confirmed that Copilot in OneNote should be functioning in my environment. During the support session they performed multiple troubleshooting and repair actions, including uninstalling and reinstalling components, repairing Office, and verifying account and licensing status. Despite all of this, the problem remained unchanged. The technician indicated that the issue appears to be on the Copilot/OneNote side rather than being caused by my local setup. Since they were unable to resolve it, they recommended that I post here in the Microsoft Tech Community to seek further escalation and visibility. Questions Has anyone else experienced an issue where Copilot can see the currently open OneNote page but cannot access the page contents? Is there a known service-side, provisioning, or feature-rollout issue that could cause this behavior? Is there a way to escalate this directly to the OneNote or Copilot engineering teams? At this point, I've been paying for the feature for roughly two months and have not been able to use the core OneNote Copilot functionality at all. Any assistance or guidance would be greatly appreciated. Thank you.A Guide to Prompt Coach

Hi folks. I recently purchased Microsoft premium so I could use Copilot in Microsoft apps and I'm wondering if there is any benefit to switching to Bing for my default search in my browser instead of Google if I have the Premium features. Such as will it profile what I'm doing offering better/more catered to me answers when searching in Bing and using in Apps? Honestly I still find the Google AI answers better but since I have this Premium version of Copilot now, I want to leverage the premium features as much as possible. Thanks.
DLP for Microsoft 365 Copilot is four behavior, Microsoft's own sources disagree on their status
"DLP for Microsoft 365 Copilot" gets talked about as one switch. Microsoft Learn now documents four behaviors, on four different schedules, and they still do not share one status. Restricting Copilot from processing sensitivity-labelled files and emails comes closest to settled. Roadmap 557255 reads "Launched", General Availability, dated April 2026. Learn states only that the feature "is available", without naming a release stage. The behavior that blocks external web search when a prompt contains sensitive info types shows on Microsoft 365 Roadmap 548671 as "Launched", while Learn gives that section no status at all. That same roadmap record carries both General Availability and Preview tags. Message Center MC1263277 was the rollout notice; it expired 31 July 2026. Blocking sensitive info typed into the prompt is the contested one. Roadmap 515945 has read "Launched", General Availability, since 14 May 2026, while Learn, edited since, still says the feature is in preview and rolling out. Verify it in your tenant before you rely on it. External email as grounding data runs the opposite way: Learn tags it "(preview)", while Roadmap 561552 reads "In development" with GA scheduled for January 2027. A setup detail that catches teams out: this is configured only through the Custom DLP template, and selecting the Copilot location disables all other locations in that policy. Confirm what content DLP actually evaluates rather than assuming it. Before you map "DLP covers Copilot," decide which of the four behaviors you need and verify each one's status in your own tenant.
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 File Downloads Expire Immediately – Error Across App, Browser, and Incognito
Hi, I’m running into a recurring issue when Copilot generates downloadable files. Every time I try to download the file (almost immediately), I get the following error message: “File unavailable. Generated files expire after a short period. Please regenerate if needed.” This happens consistently, even when I regenerate the file multiple times. I’ve tested this in several places and the issue is the same everywhere: Copilot App Browser version Incognito / Private mode The file appears for a moment, then instantly becomes unavailable. I’m unable to download anything before it expires. Is this a known issue, and is there a workaround? Thanks in advance for any guidance.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.
