Copilot Cowork mode has disappeared from the account
Hi everyone, I recently subscribed to the top-tier consumer plan (Microsoft 365 Family with Copilot / highest personal tier) to test out Microsoft Copilot. Noticeably, I am the primary subscription owner on the account. The issue: Initially, I had access to the Copilot Cowork mode/section, and it worked fine. However, shortly after, it suddenly disappeared completely from my interface, and I haven't been able to get it back since. What I've already tried: I reached out to Microsoft Support via chat, and an agent even connected to my PC remotely to troubleshoot the issue, but unfortunately, they couldn't figure out why it vanished or how to restore it. Has anyone else experienced Copilot Cowork disappearing like this on a personal/Family subscription? Is this a known server-side rollout bug, a licensing sync issue, or is there a specific workaround/setting to bring it back? Any advice or shared experience would be greatly appreciated. Thanks!MANA out-of-tree (OOT) driver for Linux LTS kernels
The Microsoft Azure Network Adapter (MANA) driver is part of the upstream Linux kernel and provides networking support for Azure Accelerated Networking. Today, we’re announcing an out-of-tree (OOT) driver, so you can use MANA on supported Linux LTS kernels without upgrading your kernel. MANA support is developed upstream in the Linux kernel, and that remains our preferred long-term model. But not every customer can move to a newer kernel quickly. Many customers maintain one standardized Linux image across Azure and other hyperscalers , and adopting a newer kernel just for Azure can mean: Building and maintaining an additional OS image Re-running security and compliance validation Changing an established patching lifecycle Waiting for Linux distribution to backport newer MANA capabilities The OOT driver gives you another option: install MANA separately and keep the supported LTS kernel you already run. How it Works? The OOT package contains the identical upstream MANA driver source, plus a thin compatibility layer that lets it build against older, still-supported LTS kernels. It is not a separate MANA implementation. Rather than upgrading the kernel, you download the source and build the MANA kernel module against the headers of your running kernel. In short: keep your kernel, install the MANA driver. Supported LTS Kernels: Linux 5.15 Linux 6.1 Linux 6.6 Linux 6.12 Linux 6.18 When to Use this OOT-Driver? If your Linux distribution kernel's already provides the MANA capabilities you need, keep using the in-tree driver. Consider the OOT driver only when: You are running a supported LTS kernel The MANA capability/feature you need isn’t available in that kernel You can’t move to a newer kernel yet You maintain a common Linux image across multiple clouds Think of the OOT driver as a bridge to the upstream driver, not a replacement for it. Support Model: The OOT driver is intended for supported, non-EOL Linux LTS kernels. Custom or heavily modified kernels fall outside the normal support scope. For long-term deployments, we recommend using the MANA driver shipped by your Linux distribution whenever it offers the functionality you need. Installing a MANA driver that is not provided or supported by your Linux distribution may affect your vendor support coverage. Before replacing the distribution-provided driver, confirm the support implications with your Linux distribution provider. Looking Ahead: MANA continues to be developed in the open Linux ecosystem, and we’ll keep working with the Linux community and distribution partners to make its capabilities available through standard kernels. At the same time, we recognize that production kernel lifecycles don’t always line up with the upstream release cycle. The MANA OOT driver helps close that gap.

After migrating to the new Microsoft Copilot experience, my personal Microsoft account lost a large part of its chat history, Saved Memories and Custom Instructions. The issue occurs on both Windows and the web. Microsoft Support performed a remote repair without success. A later Copilot update also caused a pinned conversation to disappear. During my latest support contact, the representative confirmed that this is a known issue affecting chat history, data, memory and custom instructions after migration. Microsoft engineers are reportedly working on a fix, but no estimated resolution date was provided. Service version: 2.20261026.24.0 Subscription: Microsoft 365 Family Country: Brazil Support cases: 7109794789, 7110906183 and 7110907114. Has anyone successfully recovered missing chats or had Saved Memories and Custom Instructions restored?
Copilot unavailable for other Outlook accounts and Defender won’t activate after Windows repair
Hello, I am posting here because Microsoft Chat Support directed me to the Tech Community after previously escalated support cases failed to resolve two issues with my Microsoft 365 subscription: Copilot works with my Microsoft account in New Outlook, but is unavailable when using other accounts within the same application. The Microsoft Defender app will not activate on my computer. To be clear, Copilot is not completely unavailable: it works with my Microsoft account. The unresolved issue concerns its availability for the other accounts added to New Outlook. Troubleshooting and support history I have already worked with Microsoft Support, including the Escalation Team. At their direction, I completed a repair installation of Windows 11. Both issues remain unchanged. In my latest chat, the support representative reviewed the case history and explicitly confirmed that all applicable troubleshooting steps had already been performed, including the Windows repair installation. Despite this, I was repeatedly directed to this forum. My requests to reconnect with the Escalation Team or continue the existing investigation were not accommodated. What I need clarified and investigated I suspect there may be an account-side subscription or entitlement issue, but this has not been confirmed. I need someone to establish the actual cause rather than repeat troubleshooting that has already failed. Specifically: Is Copilot supposed to be available for the additional accounts in New Outlook under my subscription? If there are restrictions, please identify exactly which subscription requirements or account limitations apply. Why will the Microsoft Defender app not activate, and can Microsoft verify whether the relevant subscription entitlement is correctly associated with my account? If an account-side investigation is required, how can my existing case be returned to the appropriate Microsoft support team? If these two symptoms have separate causes, please address them separately. I understand that community contributors cannot access my private account or internal support records. If the investigation requires that access, I need a clear route to a Microsoft team that can take ownership. I can provide my existing case reference through an appropriate private support channel. After completing an operating system repair at Microsoft’s request, I am understandably frustrated to be redirected to a public forum without a resolution or a clear escalation path. I am paying for this subscription and expect a concrete explanation of what should work, what is failing, and how it will be resolved. Please help me move this investigation forward without restarting the same troubleshooting cycle. Thank you, Christer FMicrosoft Copilot 365 Personal Premium limits
In my Copilot Notebook, I deliberately loaded 20 PDF files in order to test Copilot’s grounding behavior across the full set of available references. At the time this testing setup was created, 20 references represented the effective grounding limit described for Copilot Notebooks, meaning that these references were expected to form the source base used by Copilot when generating grounded responses. The references consisted of fully functional, original academic textbooks containing relevant and up-to-date scientific information, mostly published within the last ten years. Importantly, the sources do not differ from one another in terms of accessibility, file type, availability, or how they were added to the notebook. They are all PDF files, they are all available in the same environment, and there is no obvious difference in access conditions that would explain why some are consistently used while others are repeatedly treated as inaccessible, unavailable, summarized, or skipped. The purpose of the test was therefore not simply to see whether Copilot could access 20 files, but whether it could actually ground its answers in the complete reference set when explicitly instructed to analyze all available sources. Despite this, in approximately 99.9% of my tests, Copilot appears to ground its responses in only 3 to 5 of the 20 available references, often repeatedly using the same documents. When I ask what happened to the remaining sources, Copilot gives different explanations. Sometimes it says that it does not have access to certain files. Sometimes it says that it only received a summary of the file. Sometimes it says that a step involved in retrieving or processing the information failed. The way Copilot explains this often makes it sound as if access to the uploaded files depends on some external or intermediate system, rather than being something Copilot itself can directly control. This is difficult to understand from a user perspective because the files are already uploaded into the Copilot environment and were specifically provided as source material for analysis. The practical result is that a task explicitly requesting analysis of 20 sources often produces an answer based on only 3 to 5 of them. For academic or research use, this is a serious limitation. If 15 to 17 out of 20 carefully selected sources are not actually examined, then the final synthesis cannot realistically represent the full source base. This also creates uncertainty about what Copilot means when it claims to have used the provided materials. My question to Microsoft is: Is there a technical limit on how much information Copilot can actually retrieve, open, and analyze from uploaded files during a single task or session? If such a limit exists, what is that limit? And why, when 20 valid PDF sources are uploaded and Copilot is explicitly instructed to analyze all of them, does it so often appear to open only 3 to 5 files, while describing the others as inaccessible, summarized, or unavailable because some retrieval step failed?
Excel Copilot WebView2 crashes when rendering download links - Bug
Environment: Excel for Microsoft 365 (Desktop) Windows 10/11 - Enterprise account Issue: Excel Copilot's WebView2 panel goes completely black/blank when attempting to render download links for files generated in the Python sandbox. Steps to Reproduce: Open Excel with Copilot Ask Copilot to perform any task that generates a download link (e.g., "create a test file and give me a download link") WebView2 panel turns black immediately What I've Tried: Clearing WebView2 cache at: %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\webview2\ Copilot works normally after cache clear UNTIL a download link is requested Issue is reproducible every time Workaround: Asking Copilot to write results directly to sheets instead of generating download files works fine. This started after an Excel crash during a Copilot session.
copilot app is unable to edit an excel file and save a new version
I asked copilot to review an excel file I created and add worksheets with dashboard etc; it does the analysis, suggests the solution but when I ask to save a new edited version comes up with all kinds of limitations.. example of message : I need access to the physical workbook file in the execution workspace, not just the extracted workbook content that I can read. What I currently have is access to the contents of "book2" , including all sheets and rows What I do not have is a file path that allows me to save a modified workbook and return a new Excel file. This is exactly the distinction you were asking about earlier: ✅ I can inspect and analyse "book2". ✅ I can design the full V2 architecture you specified. ❌ In this session I cannot yet create and return the modified .xlsx because the actual uploaded file is not available in the workbook-editing workspace. I save files on OneDrive and have MS365 Family subscription , similar limitations with all MS files is it a licence issue?
