Chats desaparecido tras actualización de Copilot
Después de la actualización de Copilot, la nueva interfaz no muestra ninguna de mis conversaciones. Utilizo la misma cuenta de Microsoft en PC y móvil. Antes de que la actualización se completara, podía ver y abrir todos mis chats desde la interfaz antigua, por lo que las conversaciones seguían existiendo. Ahora la nueva experiencia muestra el historial vacío. ¿Se trata de un problema conocido de migración o sincronización del historial?
Microsoft 365 Copilot
Microsoft 365 Copilot – Persistent Source Access, Retrieval and Corpus Analysis Failures I am posting this because I have been experiencing persistent problems with Microsoft 365 Copilot when working with academic source material, and after multiple troubleshooting attempts, support contacts, and Level 2 escalation, I still do not have a meaningful explanation or solution. My use case is academic research. I work with a corpus of approximately 17–20 academic textbooks, handbooks, dictionaries, and reference works in linguistics and sociolinguistics. My goal is deliberately to test the maximum practical capacity of the subscription plan I am paying for, especially regarding multi-source analysis, retrieval, source grounding, session continuity, comparison, and synthesis. The subject matter itself is completely clear to me. I know what is contained in these sources, I am familiar with the terminology and relevant concepts, and I can independently verify whether Copilot has actually accessed the relevant material, omitted major sources, misunderstood terminology, or produced a synthesis that does not reflect the corpus. This is therefore not a case of an unclear prompt or of a user being unable to evaluate the answer. What I have already tested I have tried multiple ways of providing the source material. I have: used files stored within the Microsoft ecosystem; used OneDrive; tested Microsoft 365 Copilot; tested Copilot workflows involving Word; tested Notebook-style source workflows; rewritten and simplified prompts; created detailed protocols instructing Copilot to analyse all available sources; explicitly required source attribution; explicitly required comparison between authors; instructed Copilot not to stop at automatically generated summaries or partial retrieval output; converted the material into different file formats. The file-format testing produced one particularly strange result. Ironically, the most satisfactory results were obtained only after taking an original, fully functional academic PDF textbook — with intact indexing, tables, structured text, and no access restrictions — converting it first into an image-only PDF with no OCR, and then into an image-based PDF with OCR. These degraded versions are clearly less suitable for serious academic analysis than the original structured PDF. Nevertheless, they were among the versions for which Copilot was at least able to confirm that it had access to the document content. This is difficult to explain from a user perspective and suggests that the document retrieval or ingestion behaviour may not be functioning consistently. Main problems observed 1. Incomplete corpus analysis In one test, Copilot produced an academic-looking synthesis based on only three sources from a corpus of approximately 17–20 files. Only after being challenged did it acknowledge that it had not systematically reviewed the remaining files. For academic work, this is a serious problem. If the task is to analyse a corpus, using only a small subset without clearly stating that limitation makes the result unreliable. 2. Unreliable source access Copilot sometimes appears to know that the file exists but is unable to continue analysing it. Depending on the session, it may indicate that: it cannot access additional source content; only previously extracted content is available; it cannot continue beyond the currently retrieved material; the source is no longer usable in the ongoing task. This makes long-form source-based research unreliable. 3. Session continuity problems I have also observed behaviour suggesting that source or analysis sessions can become inactive or unusable. This is particularly problematic in multi-document work, because a corpus analysis requires continuity across multiple steps and multiple sources. 4. Summary versus source-content confusion At several points, Copilot treated a summary or summarised retrieval result as though it were effectively the available document content. The underlying files are not summaries. They are full academic textbooks and reference works. An automatically generated summary should not become the endpoint of the analysis if the full document is available. I repeatedly instructed Copilot to continue retrieving and analysing the underlying source text rather than stopping at the summary layer. Copilot itself eventually acknowledged that this would be the correct approach, but was still unable to continue consistently. 5. Weak source traceability For academic synthesis, I need to know which source supports each major conclusion. This remains inconsistent. A polished paragraph is not sufficient if I cannot reliably determine: which source was actually accessed; which authors were compared; which statement came from which file; which parts are synthesis and which parts are generic model knowledge. Source traceability is essential for academic work. 6. Task drift In some cases, after being repeatedly reminded of the original task, Copilot began suggesting unrelated outputs such as: a full course; a dictionary; exam preparation; a 30–50 page outline; other academic products. These were not requested. The original task was still to perform corpus-based analysis of a specific linguistic topic. 7. Word editing failures I have also encountered cases in Word where Copilot responded that it was unable to start editing the selected text and that nothing in the document had been changed. This adds to the impression that the issue is not limited to one specific Copilot surface. Example of inconsistent session behaviour I have also seen extremely simple requests behave inconsistently within the same Copilot session. For example, the exact same question: “What is the current time?” first received: “Sorry, I wasn't able to respond to that.” and shortly afterwards received a correct current-time response. This is obviously not an academic research task, but it is useful because it demonstrates that the instability is not always caused by complex source material. Support history I have already contacted multiple Microsoft support agents. I have also interacted with Level 2 technicians. I have submitted reports through Copilot feedback channels and through Microsoft support. I have provided detailed explanations of the behaviour. I have repeatedly tested the issue using different approaches. So far, I have not received a meaningful technical explanation of the root cause, and the behaviour has not materially changed. What I would like Microsoft to clarify I would appreciate technical clarification on the following points: What are the practical limits on the number of sources that Microsoft 365 Copilot can meaningfully analyse in one research workflow? Are there documented limits on retrieval depth within large PDFs? Why can a document be available in the Microsoft environment but still become inaccessible or unusable during the task? What causes source-analysis sessions to become inactive? Why can degraded image-based/OCR versions sometimes appear more accessible than the original structured PDF? How can a user verify which files were actually accessed and analysed? Why does Copilot sometimes operate only on summaries or partial retrieval output? Are there differences in source access and retrieval capability between Microsoft 365 Copilot, Word, Notebooks, and other Copilot surfaces? Is Microsoft aware of a wider issue involving source grounding, file retrieval, or session continuity? Is there a recommended workflow for reliable academic analysis across a corpus of 15–20 large reference works? I am not looking for another generic troubleshooting response. I would genuinely like to understand whether this is a known technical limitation, a retrieval issue, a session-management issue, or something else. I am willing to provide examples, screenshots, test cases, and additional details if that would help reproduce the behaviour. At the same time, I think it is reasonable to say that I cannot justify continuing to pay for a product if the core functionality I am paying for — reliable access to, analysis of, and grounding in the sources I provide — does not work consistently enough to be usable.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....Combining Project, Image, and Notebook Features for a Unified Experience
I'm currently using two different Copilot app experiences to manage my work, projects, and notebooks and each one excels in different areas while missing key capabilities found in the other. One app provides a much richer project management environment, with Tasks, true project folders, plugin connections, and the ability to embed instructions. The other offers a stronger, more fluid notebook experience, but lacks the depth and structure that the project-focused app provides. Switching back and forth between these environments creates friction, especially when I want my projects and notebooks to live together in one unified workspace. The separation makes the workflow feel fragmented. There are also inconsistencies across creative and experimental features. One Copilot app uses Create for image editing, while the other uses Imagen. One includes Team of Advisors, while the other doesn’t. Different experiments appear in different places, and the overall experience feels split rather than cohesive. I’d love to see these capabilities brought together into a single, integrated Copilot environment. I would love to have one place where projects, notebooks, agents, experiments, and creative tools coexist. Additionally, the video creation experience could benefit from deeper AI integration. Clipchamp is functional, but it doesn’t yet feel like an AI‑accelerated workflow. A more advanced, model video tool would dramatically improve speed and creativity for users who rely on Copilot for content production. Finally, many of us want broader access to Cowork and more agentic capabilities. The ability to design or customize our own agents would unlock huge value, especially for users who depend on Copilot for complex workflows. Right now, I often have to go elsewhere to build agentic tools because Copilot doesn’t allow enough personalization or agent creation within its own ecosystem. Bringing these experiences together ... unified projects, enhanced notebooks, consistent creative tools, richer video AI, and expanded Cowork access would create a far more powerful and seamless Copilot environment for everyone.Why is it so hard to get tech support?
The chat said they can't help me and then said to start a discussion incase a peer can help me. But its diagnosed as a back-end account issue: Based on the troubleshooting performed so far, the issue appears to be specific to your Microsoft account, as: Copilot is failing on multiple platforms (MacBook, iPhone, and web browser). The issue occurs in both normal and Incognito/InPrivate sessions. Your Microsoft 365 Personal subscription is active. Your Copilot credits are available. Another Microsoft account works normally on the same devices. At this point, I recommend reaching out to the Microsoft Copilot Technical Community, where account-specific Copilot issues can be reviewed by Microsoft moderators and specialists who can investigate service-side restrictions, account anomalies, or backend-related issues.
After a week of heavy use, Microsoft 365 Copilot is creating more work than it saves
I am posting this publicly because I want to know whether other Microsoft 365 Copilot users are experiencing similar issues. Over the last week, Copilot has repeatedly created more work instead of reducing it. The recurring issues include: Failure to consistently use information that already exists within authorized Microsoft 365 content. Incomplete deliverables that require multiple rounds of prompting and manual assembly. Loss of context during longer conversations. Conversations becoming unresponsive with no practical recovery path. Assumptions presented as if they were verified facts. Deliverables requiring manual validation before they can actually be used. A recent example perfectly summarizes the problem. While helping me prepare Microsoft feedback, Copilot generated content that exceeded the destination character limit multiple times, even after being told the limit had already been exceeded. I repeatedly had to paste the content, discover the failure myself, return to Copilot, and request another correction. The user became the validator because the AI did not validate its own output before presenting it as complete. The larger concern is that this pattern appears across many workflows. The experience often looks like this: Request submitted. Incomplete answer returned. Missing information identified. Additional prompting required. Information is finally found. Consolidation requested. Additional omissions discovered. User assembles the final product manually. That is not productivity improvement. That is transferring research, validation, correction, consolidation, and quality assurance back to the user. I would appreciate input from other enterprise users: Are you experiencing similar issues? Have you found effective workarounds? Has Microsoft discussed planned improvements around context retention, workflow continuity, conversation recovery, enterprise grounding, response completeness, and validation? I have already submitted formal feedback through the Microsoft Feedback Portal and welcome discussion from users and Microsoft representatives.
New Copilot update has made a chat inaccessible
I am experiencing an issue with a Copilot chat that appears to have become inaccessible after a recent update where the . This happened since Friday 21st August. I first noticed when all of my chats were migrated except one chat which is no longer visible in my chat history. I am logged into the same Microsoft account for the chat that is missing on which I created it. I have tried searching for it on the desktop app and in the browser with no luck. By some chance I had a Chrome browser tab open from an older Copilot session, which shows the older Copilot UI and the chat is there. The chat is fully functional: I can open it, view its history, send new messages, and receive responses. But this chat only is visible in the old UI and cannot be accessed in the new Copilot experience. The URL cannot be copied and pasted into a new tab because it redirects the copilot.microsoft.com URL to copilot.com and goes to a blank chat. The problem is if I close this browser tab, it will not be visible anymore. I have tried on the desktop app, a fresh browser tab, a fresh browser using incognito mode and even on mobile and on all of those, the new Copilot UI/Experience loads up without the chat I need. As part of my troubleshooting on the old Copilot Experience, I moved the chat to a "Project". But now I am unable to move it out of the "Project" And the new Copilot experience doesn't have a "Projects" section but instead a "Notebooks" section and I can't find it there either. You can see in both screenshots the UI is different. Because the chat now is in a Project it has a URL in the format: https://copilot.microsoft.com/projects/{project-id}/chats/{chat-id} Opening this URL on other devices or browsers redirects to the new Copilot experience and starts a new chat instead of opening the existing Project chat. As mentioned before on the new Copilot experience, this chat cannot be found anywhere else, even in the list "Chats". I can confirm that this is the same Microsoft account since my other chats have synced correctly. I have tested the URL on other browsers too with the redirect issue. The Project chat remains accessible and functional only within the old Copilot session. The chat I need contains an active, ongoing project. Although it remains accessible in the current browser tab, I have no reliable way to reopen it elsewhere, and I am concerned that if the session is lost or if I have to restart my browser or PC, I may permanently lose access to the Project chat and its accumulated context. Could you please investigate whether this Project chat is associated with an older Copilot experience, a migration issue, or a synchronisation problem between Project chats and the newer Copilot interface? Thanks, JAccepted the new Copilot update from Mac, iPhone, and iPhone and lost my entire Library
Greetings, all. I just accepted the install for a new Copilot update for my three Apple devices, and lost all pages in my Copilot Library. Microsoft promotes the sustainability of the Library storage as their AI continues to evolve and improve. But, really not happy that I've lost all of the documents where my edits to the pages were not covered in a chat conversation. Has anyone else experienced this problem and hopefully found solutions to retrieve the lost pages? I've tried to use Copilot to solve this problem without any success. Thanks, all.Recent Bug or issue i got for last 3 days when i am using Chat sessions.
Recent Bug or issue i got for last 3 days when i am using Chat sessions after creating New Projects and saving outside chats there. But in New chats when i opened and used attachment to it from Notta Memo it is clearly working its taking transcript and giving Summary and details i asked. Please help if any one faced same issue and you guys got any resolution in fixing this issue. Thanks in advance.
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.
