How does ERP MCP determine F&O environment?
How does the Dynamics 365 ERP MCP Server determine the target Finance & Operations environment when multiple environments (SIT, UAT, and Production) have MCP enabled? In Copilot Studio, the MCP connection only shows the authenticated user and does not expose any environment selection or environment identifier. Is the target F&O environment determined by the underlying Power Platform connection, the MCP client registration, a connection reference, or another routing mechanism? How can administrators verify which F&O environment an MCP-enabled agent is actually connected to?Access Issue: Copilot Agent Kit for Makers, Users cant access through Microsoft security group
Copilot Agent Kit for Makers where users granted access through a Microsoft security group can access the application, but cannot see your organization's custom templates within the Agent Library. If i individually assign the user then they are able to see it. Few more things Both the security group and individually assigned users have the Basic User and CSK - Maker roles. The issue occurs when access is provided through the security group, while direct user assignment works. The same security group works as expected for access to the customer's Copilot Studio agents.
Fix all annoying Copilot bugs
I’m experiencing an issue with Microsoft Edge on Android. Starting today (September 22, 2026), whenever I try to visit copilot.microsoft.com, Edge automatically redirects me to the Google Play Store to install the Copilot app. I prefer using Copilot in the browser and do not want to install the app. And even when i try to install the copilot app it does not let me do anything and thinks I need a license or subscription to access it like copilot is litterly supposed to be free and also even when i try to get rid of the app redirection it for some dumb reason it redirects me to from copilot.microsoft.com to copilot.com and they put in restrictions like after a lot of chats you must wait for a specific time period and a couple months ago you guys removed the ability to use copilot without registration like come on that is so dumb I want Microsoft Copilot to be fixed revert how copilot was before how is this consumer friendly
Copilot Access not working for only 1 user
Hello, I am facing an issue where I have 1 user that is unable to get answers out of the chatbot on teams. The user is opening the chatbot using the 'open with copilot' option like the rest of the team members, but when they ask a questions, the chatbot returns that it has not found information on the topic, even when the information is in the training documents the chatbot reads off of. Other users can ask the same questions and get valid answers, it is only not working for this specific user. Any suggestions on how to resolve this?
Access to Office App Context and Setting CEA as Default in Microsoft 365 Copilot
Hello everyone, I’m exploring Custom Engine Agents (CEA) in Microsoft 365 Copilot and have two questions regarding their integration with Microsoft 365 applications. Can a Custom Engine Agent access the current Office application context? When a CEA is added to Microsoft 365 Copilot, is there a supported way for the CEA to access the content of the Microsoft 365 application where Copilot is currently being used? For example: Word: Can the CEA read and/or modify the document currently open in Word? Outlook: Can the CEA access the current email/thread and perform write operations such as drafting or modifying content? PowerPoint: Can the CEA access and modify the presentation currently open? Other Microsoft 365 applications: Are similar capabilities available in other applications where Microsoft 365 Copilot is supported? Essentially, I’m trying to understand whether a Custom Engine Agent can leverage the same application context and read/write capabilities that the native Microsoft 365 Copilot has within these applications. If this is supported, what APIs, SDKs, or integration patterns should be used? Can a Custom Engine Agent be configured as the default mode? Is there a supported way to: Disable or bypass the default Microsoft 365 Copilot experience/mode, and Configure a Custom Engine Agent as the default agent/mode that users interact with when they open Copilot? For example, if an organization has a custom agent that should handle the majority of Copilot interactions, can that agent be configured as the default instead of the standard Microsoft 365 Copilot? I’d appreciate any clarification on the current capabilities, limitations, and recommended architecture for these scenarios.

Microsoft 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?Understanding Microsoft 365 Copilot Risk Surface and Mitigations
Microsoft 365 Copilot acts on the access users already have. It does not grant new permissions — it is a force multiplier that makes existing access faster and easier to discover, aggregate, and act on across Microsoft 365. That speed and accessibility can also amplify existing security and governance gaps. In environments with overshared content, excessive permissions, or inconsistent governance, users may gain faster access to sensitive information than organizations realize. It’s a shift that carries important security implications organizations should understand before scaling deployment. Customers with Microsoft 365 E5 licensing may already have access to many of the tools that can help identify and reduce Copilot-related risk, but licensing alone does not reduce exposure. What’s often missing during early Copilot deployments is a clear understanding of the risk surface itself: what data is exposed, who can access it, and through which vectors.Microsoft 365 Champion community call | July 2025 | AM
