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, JIntermittent Post-Deployment Issues with Copilot Agent Using SharePoint Knowledge Sources
Summary We are testing a Copilot Studio agent following admin approval and installation for a set of users before we launch it to everyone in the organization - the objective being to test out the end user experience and check that everything is working fine. We have encountered several inconsistent behaviours using the agent across both the Copilot app and Microsoft Teams. The issues seem to be resolved after signing out, restarting the application, or signing in again. 📍Looks like a lot of instabilities and poor end user experience with this method & this is blocking us from launching the agent to the organization. Agent Setup Agent built in Copilot Studio & deployed via pipeline (Development > QA > Production) Knowledge source 1: SharePoint connection using Dataverse indexing/synchronisation Knowledge source 2: Live SharePoint connection Tested in the following apps after admin approval/publishing/pinning: Microsoft Copilot app Microsoft Teams Issues observed Agent not visible in Copilot app After agent is approved, installed, shared and pinned (to specific users) from Admin side, the agent is not visible in Copilot app. We gave it over 8 hours after the admin process. Agent appeared after signing out of Copilot app and signing back in again. SharePoint connection consent prompt not displayed Users are expected to receive a prompt with consent to connect to SharePoint (with "Allow" button). What appears is only a message but no card with the "Allow" button. This started working after signing out of Copilot app and signing back in again - so the sign out + sign in had to be done twice Responses not retrieved from Knowledge source 1 In spite of proceeding with the "Allow" prompts, for some users, the responses are coming only from Knowledge source 2 (live connection) & not Knowledge source 1 (connection with dataverse indexing). This is seen both when interacting with the agent in Copilot app and Teams. For some users, this was fixed after signing out and back into the apps Questions Has anyone experienced such instabilities with admin deployment/publishing of agents? If yes, what have you done to sort them out and have you been able to successfully launch agents organization wide with this approach? Does anyone know about known issues/glitches with admin deployment/publishing of agents? We did not see these issues when sharing the agent using Copilot Studio.How to Fix Microsoft Copilot Not Working on Windows: Easy Solutions That Actually Help
Microsoft Copilot can be a genuinely useful Windows companion. Whether you use it to brainstorm ideas, summarize information, create images, find answers, or get help with Windows settings, it can save a surprising amount of time. But when Copilot suddenly refuses to open, gets stuck loading, crashes, shows a blank screen, or simply stops responding, the experience can be frustrating. Link to the postAccepted 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.
Copilot Chat Retention vs Memory: What Happens to Chat History Inferences?
How do Chat History inferences behave after tenant retention deletes the underlying Copilot interactions? Microsoft's documentation explains that: Saved Memories persist until explicitly deleted. Chat History personalization creates inferred details. Purview retention policies do not apply to Copilot Memory. What is unclear is the lifecycle of Chat History inferences when the Copilot interactions that originally contributed to those inferences are permanently removed by a tenant retention policy. Example: A tenant has a 60-day retention policy for Microsoft 365 Copilot interactions. Copilot infers user preferences from conversations. The source conversations are later removed due to retention. Does Copilot: Retain those inferred details? Recompute them from remaining conversations? Remove them because the source interactions no longer exist? Understanding this is important because users may experience changes in Copilot personalization without understanding why.Recent Bug or issue i got for last 3 days when i am using Chat sessions.

Hello, I was able to isolate an issue related to Copilot Call Delegation and compliance recording applications. We have successfully configured Copilot Call Delegation and confirmed that it functions as expected in a standard Teams Phone environment. However, when a compliance recording application is assigned to the user, Copilot Call Delegation no longer works correctly. The Copilot delegate does not join or participate in the call as expected. Has anyone else encountered this behavior? Is there a known limitation, compatibility issue, or recommended configuration when using Copilot Call Delegation alongside Teams compliance recording solutions? Any guidance from the Microsoft product team would be greatly appreciated. Thank you.Update: Root Cause Identified
Hi everyone, I would like to share the root cause and solution in case someone else encounters the same issue. The Problem I created several agent flows directly in Power Automate using: https://make.powerautomate.com The flows were configured correctly: The flow starts with When an agent calls the flow The flow ends with Respond to the agent The flow and agent are in the same environment The flow is included in a solution The flow is published and fully functional The flows could be added to an agent and executed successfully. However, unlike flows created directly from Copilot Studio, they did not appear in the Global Tools directory. What I Investigated I verified: Trigger configuration Respond to the agent action Environment consistency Solution membership Publish all customizations Asynchronous response settings Synchronization delays between Power Automate and Copilot Studio None of these were the root cause. Root Cause The issue was related to the workflow Plan. I discovered that: Flows created directly in Power Automate were assigned: Plan = The user running the flow Flows created directly in Copilot Studio were assigned: Plan = Copilot Studio Although the Power Automate flow was fully functional and could be used by the agent, it was not visible in the Global Tools directory. Solution After changing the workflow Plan to: Plan = Copilot Studio the flow immediately appeared in the Global Tools directory. Configuration Location The setting can be found in the workflow properties under: Primary owner → Plan Important Note Based on my testing, changing the Plan to Copilot Studio appears to be a one-way operation and may not be reversible. It may be a good idea to export or save the flow before making the change. Acknowledgements Special thanks to sohnash for reproducing the scenario and providing troubleshooting suggestions, and to Patty_Velasquez for sharing similar observations that helped confirm the behavior. Hopefully this helps others who encounter the same issue. Best regards, Adhonaï KOUKAFree Copilot Credits for MCTs/ MVPs ?
Hello All The new Copilot Studio experience, powered by the GitHub Copilot harness, requires Copilot Credits for building, testing, and evaluating agents. In contrast, classic Copilot Studio requires Copilot Credits only after publishing. Is there a way for MCTs or MVPs to get Free access to Copilot Credits so they can test agents in the new Copilot Studio experience?
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.
Copilot Notebook features missing
I think it was back in March or April that improved features for Notebooks in Copilot were added as General Availability: the Audio overview, Mind Map and others. I have Copilot Premium, can and have created a notebook, but those features are greyed out for me. I'm pretty sure I have enough content (3 files with approximately 500 pages of content) in the Notebook but when I click those buttons, I see a message: More in OneNote Power BI Notebook isn't available here yet, but coming soon. For now, you can open it in OneNote. Those features are in OneNote, but not in Copilot. What's wrong, and what can I do to get them working in Copilot Notebooks? Thank you for your answer
What is the best file format for an AI agent knowledge base?
This is a best practice sharing the best format for an agent and show you why you should convert your PPT, PDF, WORD into a TXT markdown. I had an issue with my agent, time taken to answer was too long, and usually we spend a lot of time asking: What is the best prompt? Why is my agent slow? Why does retrieval sometimes work and sometimes fail? How can I improve answer quality? But I realised I was asking another question much less often: What is actually the best file format for the knowledge base? PDF? Raw text? Markdown? Pre-chunked text? Semantic sections? Context-enriched text? And more importantly: How much does the format alone affect agent performance? I tried to find a quantified benchmark answering this specific question, with the same agent, same source knowledge and same questions, but different knowledge representations. I couldn't find one that really answered what I wanted to measure. So I decided to run the experiment myself on a real case. My first exploratory tests were already surprising: depending on the representation, the agent could be significantly faster and more accurate, despite working from the exact same source information. So I decided to push the test further. My objective I want to identify, without assumptions and based on actual evaluation data, how a long document should be prepared for an LLM knowledge base so that the agent can retrieve, understand, ground and answer from it as reliably as possible. I focused on five dimensions: Answer quality Retrieval reliability Source grounding / citations Execution time Robustness across single-turn and multi-turn questions The broader question I'm trying to answer is: How should we structure knowledge so that an LLM can retrieve and use it as reliably as possible? The test case I deliberately chose a document that isn't particularly friendly for RAG: a 46-page European regulation, https://eur-lex.europa.eu/eli/reg/2011/1169/oj?locale=fr, on the provision of food information to consumers. The information is distributed across articles, definitions, exceptions, annexes, tables, numerical thresholds and cross-references. That makes it useful for testing retrieval: answering correctly often requires finding a very specific piece of information while preserving enough context to understand how it applies. I used the native PDF as the baseline and created 6 additional knowledge-base representations of the same document: Raw TXT Markdown Chunk-ready TXT RAG-oriented units Semantic TXT Contextual TXT One rule: same knowledge, same agent, same instructions, same questions. Only the knowledge representation changes. The benchmark I used two evaluation sets: 42 single-turn questions testing broad coverage of the document: direct facts, thresholds, exceptions, annexes, lists and cross-references. 5 multi-turn conversations containing 13 questions, to see what happens when a user asks a question and then follows up with things like: "And in this case?" "What are the exceptions?" "And for dietary fibre?" This gave me: 47 evaluated test cases / 55 actual questions per format Across all 7 formats: 329 evaluated conversations 385 user questions executed First results Metric Native PDF Best structured representation Overall pass rate 66.0% 85.1% - Contextual TXT Best single-turn score 69.0% 88.1% - Chunk-ready TXT Multi-turn benchmark 40% 80% - Contextual TXT Multi-turn execution time 14m24 5m54 Total benchmark time 44m31 24m49 The quality gap was already substantial: 66.0% → 85.1% That's +19.1 percentage points while keeping the underlying knowledge unchanged. I also saw a major difference in execution time. On the multi-turn test: 14m24 → 5m54 That's approximately 2.4× faster. Across the complete benchmark: 44m31 → 24m49 Around 44% less execution time. These timings represent the complete agent evaluation pipeline, so they shouldn't be interpreted as pure LLM inference latency. But the difference under identical test conditions is large enough that I want to understand it better. Findings There wasn't one format dominating every benchmark. Chunk-ready TXT scored highest on independent questions: 88.1%, while Contextual TXT performed better across multi-turn conversations and finished with the highest overall score. That may suggest that the way we optimise a document for isolated retrieval isn't exactly the same as the way we should prepare it for conversational retrieval. In the contextual version, I tried to make every section understandable when retrieved independently by keeping useful information around it: Source references Section context Retrieval cues Relevant cross-references For regulatory documents, this seems particularly important. A numerical value retrieved alone can be meaningless without knowing which rule it belongs to, under which conditions it applies, and whether another article contains an exception. Where I am now This remains an exploratory benchmark: One document One domain One agent setup One evaluation framework One run per configuration There are plenty of things I still want to test: repeated runs, retrieval-level evaluation, token consumption, larger knowledge bases, other document types, chunk sizes, overlap, contextual headers, and more. But these first results already convinced me that the preparation of the knowledge base deserves much more attention when evaluating an agent. We often spend hours refining instructions while the same information may behave very differently depending on how it reaches the retrieval layer. Next step I'll share the prompts, knowledge-base formats and evaluation methodology on GitHub so the experiment can be reproduced and challenged. I'll keep enriching the repository as I test new formats, improve the evaluation set and add new results. If people here have ideas, edge cases or formats worth testing, I'd genuinely like to include some of them in the next iteration. What would you test next?Created agents are shown twice in "Shared with you"
Hi all I've noticed for myself, and for several of our users, that when agents are created in Copilot Studio, and shared. Each agent is shown twice, when people access their "Shared with you" in Copilot. Why is that, and does anybody else experience this?

Free, read-only PowerShell tool to find SharePoint oversharing before enabling Copilot
The first time I pointed my own tool at a tenant, it found three sites the whole company could open. A search center was one of them. Nobody had shared them on purpose. They came that way, and Copilot would have read every one. That is the thing people ask before a Copilot rollout. What will it actually surface. Copilot only returns what a user can already open, so the real exposure is the broad access that was already there. The Everyone and Everyone except external users grants. The anonymous and organization-wide links nobody remembers making. Microsoft has reports for this and they sit inside the paid SharePoint Advanced Management add-on. For teams without that license I put together a free open-source PowerShell module that answers the same question. Sharing it here in case it helps someone planning a rollout. What it does Get-EveryoneAccess finds every place the Everyone and EEEU claims grant access, on one site or the whole tenant. Get-OversharedContent finds the anonymous Anyone links and the organization-wide links. It reads them from the hidden SharingLinks groups instead of walking every file, so it stays quick on a big tenant. Invoke-CopilotReadinessAssessment runs both, scores the exposure out of 100, and writes an HTML readiness scorecard you can hand to your security team. Install Install-Module CopilotGovernance -Scope CurrentUser It is read only. It reports, it never changes anything. It needs PowerShell 7 and PnP.PowerShell and your own Entra app client id, because PnP 3.x no longer ships its own sign-in app. It also reports coverage, so a site it could not read is flagged and never counted as clean. Being upfront about the limits today. It scans each site and its lists, and subwebs are still on the roadmap. Links created as Flexible on the newer sharing experience can be under-counted, so pass -IncludeSpecific to review every link. The module is on the PowerShell Gallery at powershellgallery.com/packages/CopilotGovernance and the code is on GitHub at github.com/gvijaikumar9/CopilotGovernance Feedback and edge cases welcome. Happy to fix what people hitIs there any benefit to using Bing for my default search if I have Copilot Premium?
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.Power Automate Flows Created Outside Copilot Studio Not Appearing in Tools
Hello everyone, I'm facing an issue with Copilot Studio and would appreciate your advice. Context I have several Power Automate flows that I created directly from: https://make.powerautomate.com My goal is to use these flows as tools within a Copilot Studio agent. All components are in the same Power Platform environment. What I've verified The flows use the "When an agent calls a flow" trigger. The flows end with "Respond to the agent". The flows are saved and published. The agent and flows are added to the same Solution. The solution has been published. I am using the same account and environment for both Power Automate and Copilot Studio. The Issue Flows that are created directly from Copilot Studio appear correctly under: Tools → Add Tool However, flows created from Power Automate (make.powerautomate.com) do not appear in the Tools list, even though they have the same trigger and response configuration. Question Are there additional requirements for a Power Automate flow to be discoverable by Copilot Studio? For example: Does the flow need to be an Agent Flow rather than a standard Cloud Flow? Are there known synchronization or caching issues between Power Automate and Copilot Studio? Is there a specific setting, solution configuration, or publishing step that I may have missed? Any guidance or experience with a similar issue would be greatly appreciated. Thank you!Copilot as an HR analyst with sharepoint connection?
So we've been having these conversations about using Copilot a bit more effectively. Right now, we have all these surveys, reviews, and feedback templates people have filled out, and it's all in our SharePoint. I know I can manually take and upload them to copilot and it can give me summaries etc. Can I connect it to specific folders so it always accesses them without me manually uploading and gives me bulk analysis? Engagement trends, review score averages, etc.
