Seeking Guidance on Microsoft 365 Copilot Adoption Support for an Enterprise Customer
Hi Everyone, We are a newly enrolled Microsoft partner currently working with a customer to accelerate Microsoft 365 Copilot adoption across their organization. We are exploring how we can best support the customer and would like to understand whether there are any Microsoft programs, resources, partner managers, or engagement channels available to help us collaborate with Microsoft on Copilot adoption opportunities. Could anyone advise on: The recommended Microsoft channel/team to engage for an enterprise Copilot adoption opportunity Any Microsoft programs or resources available to support customer adoption How partners can collaborate with Microsoft for customer-specific Copilot adoption support Any guidance on the appropriate Microsoft team, program, or point of contact would be greatly appreciated. Thank you!
Copilot Legal Agent in Microsoft Word
Can anyone tell me if the Copilot Legal Agent in Microsoft Word has been withdrawn from Frontier? Frontier is enabled and I can see other Frontier agents, MS word desktop App updated to latest build I have a Premium Copilot Licence but cannot see the agent. I previously thought I had seen it somewhere (I work across many tenants) but can no longer see anywhere.
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.Help.I have 365 Premium subscription, it hasn't expired, but I lost access to Copilot on phone.
I'm an Office 365 premium subscriber. I used to be able to use Copilot normally on Office on both my computer and iPhone, but now I can only use Copilot on Office on my computer. When I try to use Copilot on Office on my phone, it says: 'It seems you don't have a valid license. To get access, please contact your admin.' Before this problem happened, I sent an invite link to someone else to use Office 365 with me, and then I clicked the invite link myself on my phone using my subscriber account, and it showed that I successfully joined the sharing. After that, I couldn't use Copilot on Office on my phone anymore. Even though my subscription account is still shown as the organizer in the Family group and my subscription hasn't expired, it seems like I lost access to Copilot on my phone.
Custom Agent Builder agent suddenly failing with "Oops, something happened" - no config changes
Hi All, We built a custom agent in Agent Builder (Microsoft 365 Copilot) that generates a Word risk assessment by grounding on a contract (either the document currently open via the Word Copilot add-in, or a file uploaded in the web browser chat), plus a fixed set of knowledge sources (guidance notes, playbooks). It worked reliably for about 5 days while I was testing it solo. We then rolled it out to appr. 20 users, and shortly after, it started failing consistently with a generic "Oops, something happened, try again" error, typically after a long delay, in both the Word add-in and the browser version. I can't confirm causation, but the timing lines up closely with when we expanded from single-user testing to ~20 concurrent users. I don't know whether this points to a tenant-level capacity/concurrency limit being hit, or its something else, just stating it in case others have seen a similar threshold effect. Is this a known concurrency/capacity limit for Agent Builder agents once usage scales up, or a separate backend regression affecting document grounding, and has anyone else seen this pattern after moving from single-user testing to broader rollout?Need live support to get rid of Copilot and resolve billing
How do I contact a live support agent to get rid of Copilot and address billing issues? I need a passkey but cannot get one or contact a live support agent any other way the system has been running me around in circles. When I call the support number I need a passkey. But I cannot get a passkey under my admin support options. I subscribed directly through Microsoft and am the admin and sole user. I urgently need to get rid of Copilot from Word so I can use a specialized AI software for my business. It is designed to work in Word but has known conflicts with Copilot. The new software suggests change to my documents but cannot implement them because of Copilot. This interference is a known issue. Buying a second Business Standard subscription without Copilot and switching to that has not resolved the problem. I have tried logging out and in again, and clearing my cache. I am using the desktop version of Word. Billing and subscriptions are also an issue. My Business Standard plus Copilot subscription says "expired" and the three dots by the product don't give me any option to cancel or manage the subscription. But I also got a notice on June 18 that the annual subscription had been renewed, and that it will renew again in one year. I have not paid the most recent invoice. I don't want to test whether I would get more options by paying, since I don't want the copilot subscription and it is marked expired. I would appreciate any help on (1) disabling Copilot without disabling other connectors and (2) contacting a live person to address billing issues.
Feature Proposal: OS-level Intelligent Task Organizer (Windows + Copilot)
A Idea about Intelligent Tasks organizer, I have to remember a lot of things during the team meetings like what is been said (we'll schedule a call or follow up etc.,) and what has been communicated in the emails (I'll get back to you after 2 weeks, or call us after two weeks) , And notes that I took in the notepad, or notepad ++,or sticky notes, or word, or one note. I want to chronologically display tasks on the right hand side of the laptop screen just like sticky note and it shall display all tasks one by one, it shall remove tasks are already complete (email sent with confirmation). and arrange, adjust every few mins according to priority/time or user added priority. App shall display small icon (just like chat) upon clicking it shall display ordered list of tasks. and desktop apps like teams/note/word/notepad++,sticky notes can participate by default or other apps like notepad++ can be onboarded manually in to the app. You can use a local model which infers the meaning of “I’ll call you in two weeks” - who is “I”? you or them? “Let’s follow up later” - task or casual statement? “I sent it” - which task did this complete? You can use a local model such that Corporate Teams/Outlook access may allow by corporate policy. Need to put much emphasis on false positives if the app keeps inventing tasks. Do not need to bring big LLMs in to the picture for inference, because of corporate policies may not allow. Microsoft provides operating system,office 365, tools with copilot, the inference can be possible because of all apps/content can be accessible at os level. Problem: Users capture tasks across multiple tools: Teams meetings and chats Outlook emails Notes (OneNote, Notepad, Sticky Notes, Word) Tasks become fragmented, untracked, and often lost. Proposed Solution: A lightweight system-level task layer integrated with Windows + Copilot that: Core Features Automatic task extraction From Teams, Outlook, notes, and user text Example interpretations: “I’ll call you in 2 weeks” “Let’s follow up later” Context-aware inference (local model) Identify: Task owner (“I” vs “you”) Priority signals Deadlines Minimize false positives Chronological task timeline Tasks auto-organized by: Time Priority Recency Floating task panel (desktop UI) Docked widget (like Sticky Notes or chat bubble) Expand/collapse view Always visible option Automatic task lifecycle tracking Detect completion: “Email sent” “File shared” Remove or mark complete automatically Continuous re-prioritization Adjust every few minutes based on: New inputs Deadlines User behavior Privacy-first architecture Use local models (SLM) instead of large cloud LLMs Enterprise admin control for data access Why this matters: Millions of users manually track tasks across fragmented tools, losing productivity daily. This feature would unify task understanding across the OS and M365 ecosystem.What’s New in Microsoft 365 Copilot | May 2026
