Copilot returning document context error
I was using Copilot in PowerPoint to create presentations from Word files, without problems. Without changing anything, PowerPoint suddenly started returning an error when I opened the Copilot pane. This issue is only occurring on one computer, whereas my other laptop, using the same account, is working properly. I have tried signing out/in of my account and also reinstalling 365 on this computer. Error code: Error Message: Cannot read properties of null (reading 'DocumentContext') Error Stack: TypeError: Cannot read properties of null (reading 'DocumentContext') at https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/appchat.js:1:841804 at Object.useMemo (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:100202) at t.useMemo (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:34060) at _i (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/appchat.js:1:841672) at ua (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:94279) at Xl (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:146207) at zu (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:133543) at Iu (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:133471) at Ou (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:133334) at Cu (https://fa000000129.resources.office.net/033f92d3-bc6d-439a-858a-a17acf70360a/1.0.2509.1003/en-us_web/taskpane.js:2:130331)
Copilot Agent in SharePoint App
I created a new Copilot agent (using GPT-4) that refers to knowledge from SharePoint sites and published to SharePoint site. I configured 'Authenticate with Microsoft' under 'Security'. Approved the agent from SharePoint site and set as 'default' for the site. It works as expected when launched from a SharePoint web page. However, when the agent is launched from SharePoint app, it says, 'connect to your Microsoft account' and if I click Sign in button, it throws an error 'Cannot connect'. Then the agent fails. What am I missing here?
🚀 A Proposal to Eliminate Copilot Fragmentation and Unify the UX
🚀 A Proposal to Eliminate Copilot Fragmentation and Unify the UX Body (English first) Currently in Microsoft 365, there are multiple entry points for Copilot — Copilot Pages, app-specific Copilots, and Copilot in Loop. This fragmentation often confuses users about which Copilot to use and where the outputs are saved. I propose a simple unification: ol {margin-bottom:0in;margin-top:0in;}ul {margin-bottom:0in;margin-top:0in;}li {margin-top:.0in;margin-bottom:8pt;}ol.scriptor-listCounterResetlist!list-758aeff6-9418-422e-b90e-e34b3c8e9a540 {counter-reset: section;}ol.scriptor-listCounterlist!list-758aeff6-9418-422e-b90e-e34b3c8e9a540 {list-style-type:numbered;}li.listItemlist!list-758aeff6-9418-422e-b90e-e34b3c8e9a540::before {counter-increment: section;content: counters(section, ".") ". "; display: inline-block;} General-purpose Copilot → Copilot Pages only Even when opening Word/Excel/Outlook/Loop via the sidebar, all interactions are handled by the Copilot in Copilot Pages. Specialized Copilot → Toggle switch Add a toggle at the top of Copilot Pages (“General ↔ Specialized”) to switch into app-specific Copilot functions only when needed. Save format → Standardize to Loop files All generated content is saved as .loop files in OneDrive/SharePoint and can be directly opened in the Loop app. Benefits ol {margin-bottom:0in;margin-top:0in;}ul {margin-bottom:0in;margin-top:0in;}li {margin-top:.0in;margin-bottom:8pt;}ol.scriptor-listCounterResetlist!list-758aeff6-9418-422e-b90e-e34b3c8e9a541 {counter-reset: section;}ol.scriptor-listCounterlist!list-758aeff6-9418-422e-b90e-e34b3c8e9a541 {list-style-type:bullet;}li.listItemlist!list-758aeff6-9418-422e-b90e-e34b3c8e9a541::before {counter-increment: section;content: none; display: inline-block;} Eliminates confusion caused by Copilot fragmentation → more intuitive UX. Users only decide “general or specialized” → very simple flow. Future apps can be added via the sidebar → high scalability. 👉 In short: “General = Pages, Specialized = Toggle, Save = Loop” This would greatly simplify and improve the Copilot experience. If you agree, please give it a like 👍 日本語版（for Japanese users） Copilot乱立を解消し、UXを一元化する提案 現在のMicrosoft 365では、Copilot Pages、各アプリ専用のCopilot、Loop＋Copilotなど複数の入口が存在し、ユーザーが「どのCopilotを使えばよいのか」で混乱しています。 以下のように統一することを提案します： 汎用CopilotはCopilot Pagesに一本化 特化型Copilotは切替トグルで呼び分け 保存形式はLoopファイルに統一 効果 乱立による混乱がなくなり、UXが直感的に。 導線が「汎用か特化か」の選択だけに。 将来アプリが増えてもサイドバーに追加するだけで拡張可能。 👉 一言で言えば： 「汎用＝Pages、特化＝トグル、保存＝Loop」 これでCopilot体験は大きく整理されます。 ご賛同いただける方はぜひ「いいね」をお願いします！ 👍
Deleting AI developed meeting recaps
Hello, We have recently begun utilizing the meeting transcript and AI generated transcript functionality for our meetings. However, we can discuss potentially sensitive information on our calls and so we would like to understand how to delete the AI notes from the recap once we have had adequate time to digest and review. I can see how to delete the full transcript, but I do not see an option to delete the AI meeting notes. And we need to confirm that once deleted they are cleared for good and cannot be deemed discoverable. Thank you for help that anyone can provide.
Researcher - Formating Issues
I have a serious issue to force Researcher to follow a specific format concerning citation within his response. Although it delivers a superior content, it does not comply with neither the instructions (word file) nor the template nor the prompt concerning the citations. I want clickable (hyperlinked) citations throughout the text that will be listed in a references section at the bottom of the report. I re-engineered instructions, template and prompt 100s of times according to it's own suggestions without success. It always miss something. I also prompted "not to synthesize anything untill the Template and Instructions rules applied". Again failed. Are other folks having similar challenges? Did you found any tips or tricks to force Researcher to comly in formating requests?
Copilot Task Switching
Are there any planned enhancements to improve task-switching UI features or enable docking of Copilot chats and agents for easier return and continuity? Our users frequently engage with Copilot across multiple workflows throughout the day and often struggle to locate previous prompts. For example, a sales representative might begin a client proposal in Researcher, pause to retrieve a document for their manager, use Writing Coach to format an email to a leader, and then want to return to the original Researcher prompt. Simultaneously, they may run a skill builder agent during their lunch break. These transitions can be challenging without a more robust way to manage and revisit Copilot interactions. As a suggestion, it would be helpful to have the ability to pin active tasks or Copilot sessions to the left-hand navigation bar, allowing users to quickly return to key workflows without losing context.
Crowdstrike EDR repeatedly flags m365copilot_autostarter.exe
We are seeing recurring CrowdStrike informational alerts for m365copilot_autostarter.exe, located under the WindowsApps directory for Microsoft OfficeHub (versions 19.2509.32081.0 and 19.2508.51171.0). The alerts are flagged as “meeting the machine learning-based on-sensor AV protection’s lowest-confidence threshold for malicious files”. Two hashes are repeatedly seen across different customer environments: - 2ee039508706a40e1ca608d2da670d8f8b4b3605343ae4601e7f2407db6a35e (timestamp: Sept 2, 2025) - ade2675e1247ffd1cbe4e408716a559fb502aeca26985a53d35755d1c13827f3 (timestamp: Aug 21, 2025) Both files appear clean in reputation checks, but they are unsigned and have no vendor information, which is raising questions in security tooling. Since these alerts are consistently triggered across Windows 10 and 11 endpoints in multiple environments, we are trying to confirm: - Is this a legitimate, recently introduced OfficeHub / Copilot component? - Why is it unsigned compared to other OfficeHub binaries? Any clarification from Microsoft would be appreciated.Microsoft Explains the Differences Between Copilot Memories
Copilot memory is a term that refers to different things, including Copilot communication memory, a method to use the Graph to personalize responses for users. The idea is to use all the sources of information available through the Graph as Copilot responds to user prompts in Microsoft 365 apps instead of limiting sources to whatever the app works with. It’s a good idea, providing the Graph sources are accurate. https://office365itpros.com/2025/09/03/copilot-memory-types/
