Copilot Studio + SharePoint: Markdown (.md) Files in Doc Libraries Supported as Knowledge Sources?
Hi all, We’ve been doing some deeper testing with Copilot Studio agents grounded in SharePoint knowledge sources, and I’m hoping to clarify whether what we’re seeing is a known limitation or an undocumented gap. Scenario A Copilot Studio agent uses SharePoint document libraries as a knowledge source The library contains Markdown (.md) files that are intentionally used as canonical design references The same .md files: ✅ Work well when uploaded directly to the agent ❌ Are not retrievable or citable when stored in a SharePoint library and added as a SharePoint knowledge source To help with grounding, we created modern SharePoint index pages that: Explain what the markdown collections are (Patterns, ADRs, Guardrails) Link directly to the canonical folders and files Explicitly state that the .md files are the source of truth The agent can: Discover and summarize the index pages correctly Understand that .md artifacts exist and where they live But it cannot: Read the content of the individual .md files Apply a specific pattern or ADR from those files in a design conversation Cite them as sources, even when permissions and search indexing are confirmed What We’ve Checked Permissions (agent user has access) Folder depth (kept shallow) Search results (markdown files appear in SharePoint search) SharePoint indexing status Work IQ enabled Same content works when attached directly to the agent This behavior also seems consistent with what others have reported here: Markdown works when uploaded directly Markdown retrieval degrades when hosted in SharePoint libraries Questions for the Product Team / Community Are Markdown (.md) files in SharePoint document libraries officially supported as Copilot Studio knowledge sources today? If yes, are there specific constraints (file size, rendering, parsing, indexing) that differ from Word/PDF? If no (or “not yet”), is this a known limitation on the roadmap? Is the recommended pattern to: Convert important markdown files into .aspx pages, or Use thin “index / summary” pages and keep markdown canonical until retrieval improves? We’re happy to adapt our information architecture — just trying to align with the intended platform direction rather than work against it. Thanks in advance for any guidance or clarification. This capability is extremely powerful, and clearer expectations here would help a lot of teams make the right design tradeoffs.
Agent response duplicated in email
Hi, I have created a Copilot Studio Flow which has 3 agents. 2 agents do some research in parallel, I catch the results in 2 different string variables and hand the variables over to a third agent. The third agent should merge both variables, format them and hand them over to "Send Email". In the email body I add the output of agent 3. The workflow itself works. But I always have the complete email body text twice in the email received by the recipients. Where is the duplicate of the agent output coming from? I have this issue also when I add the agent response of agent 1 and agent 2 directly to the "send email" node. Does anyone have an idea? Would be great to get feedback. Appreciate it. Thanks!
New experience workflow can't use dynamic value in Business central connector bool
Hi all As the title states I have run into an issue when trying to use the Business central connector in a new experience workflow to create a record in my sales invoice lines. I am trying to create a prototype for an agent that can create invoices in my Business central environment based on certain criteria given by my customers. To let the agent do things in Business central I am trying to create workflows for it to use as tools, but when trying to add sales lines to the invoice, I can't seem to use dynamic values in two boolean fields, it only shows a dropdown with true/false. I know I could use a condition and use the create record four times depending on the combination of the two fields, but that seems messy, especially when this was possible back in power automate flows. Has anyone experienced this and do we know if this is considered a bug or won't it get fixed?
Copilot Studio agents problems connecting to Sharepoint knowledge source
Hello, Since last week users in my tenant are experimenting issues regarding the connection between copilot studio agents and Sharepoint. The agents are not able to extract information from Sharepoint sites, printing there is not information in the Sharepoint site regarding the user's question when that information is in Sharepoint. These agents used to work well till last week. Does have been any update in Microsoft 365 services that can be affecting these agents ability to retrieve information from Sharepoint?
Copilot Studio consistent System Error issue
I have built an agent that invokes a Power Automate flow as a tool. Inside the flow, I'm using the Execute Agent and Wait activity, which calls another agent. This execution takes around 10–15 minutes to complete, after which the flow returns the result using Respond to Agent (asynchronous response). Although the flow completes successfully and the downstream agent finishes its execution, the calling agent still receives a System Error instead of the expected response. Why I'm using a Flow instead of directly connecting the agent Normally, I would connect the agent directly. However, the agent being invoked is already connected to another agent. Since agent → agent → agent chaining is not supported in Classic mode, I used a Power Automate flow as an orchestration layer to work around this limitation. Looking for someone who have faced this issue and has any solution to this.Copilot Studio Agent for Excel Macro Modernization — Anyone Tried This?
Anyone built a Copilot Studio agent to analyze macro-enabled Excel workbooks (.xlsm) and recommend a modernization path — e.g., migrating logic to Power Automate or rebuilding as Power BI dashboards? Curious about real-world attempts: what worked, what didn’t, and where the ROI actually showed up. Would love to compare notes before diving in myself. #CopilotStudio #Excel #PowerAutomate #PowerBI #PowerPlatformFile processing capabilities in new Copilot Studio
In the classic version of Copilot Studio there is an option in settings to enable file uploads by users. This setting does not appear to be present in the new Copilot Studio settings and I have noticed that I am unable to upload a file to the agent when public via the MS365 Copilot channel. Has anyone else experienced this issue with the new Copilot Studio?Looking for ideas: Reducing "Allow" prompts when using SharePoint Knowledge
Hello community members! I'm hoping to get some advice from people who may have come across a similar challenge with their Copilot Studio "SharePoint knowledge retrieval" agents 🤞 Current setup Agent set up in Copilot Studio and published to channels - M365 Copilot and Teams Agent is connected to 4 SharePoint folders (I'm using Method#1 - see below screenshot for reference). This is essential because the documents inside the folders contain both text and image-based content. This is the only method that brings results Users have permissions to access the content in these folders Problem We are currently preparing to roll out this agent but we've hit a user experience issue that is becoming a blocker for moving forward. When a user interacts with the agent for the first time, they are asked to click "Allow" ... 4 times .. one for each of the folder that the agent is connected to This experience feels heavy for users (based on our pilot feedback) and people give up after the first or second time because they think it is not working. In spite of comms and a video about having to repeat this action until done. We want the first time experience to be as smooth as possible to drive adoption. Also, we are going to expand the solution to include more folders soon - so there is also a concern that number of consent prompts could grow further. What I've tried Used Method#2 to connect to SharePoint folders. While this didn't pop up the "Allow" prompts, as indicated earlier, this approach doesn't work because it doesn't return any results from documents as they contain both text and image content. Tried Method#1 to connect to the library (and use instructions to indicate necessary folders) - this didn't work because the method doesn't allow to connect to libraries. Note - I cannot restructure the library and put all the documents into one folder because that's the way the documents have been maintained for a long time & direct links to the folders are being used across the organization via. emails, decks etc. Looking for advice Has anyone found a way to reduce or eliminate these consent prompts? Are there any other recommendations on using SharePoint as a knowledge source that respects user permissions without these consent prompts? Does anyone know why Method#1 and Method#2 have different user experiences where the first one prompts for consent and the second doesn't?Deterministic way to mark generative answer output as AI-generated - AI Act
Hi all, We have a text-based RAG agent in Copilot Studio using the Azure AI Search connector as the knowledge source. It's customer-facing. We need every generated turn to carry a machine-readable marker identifying it as AI-generated, not just a visible disclaimer line. Instructing the model to append something isn't acceptable for us, because it's non-deterministic and can be prompt-injected away. Has anyone found a cleaner pattern? Like how to do it?All Copilot Studio Workflow Tools Suddenly Returning HTTP 403 Before Execution
Hello Copilot Studio Community, I am experiencing an authorization issue with multiple workflows connected to an agent built using the Copilot Studio new experience and new Workflows experience. These workflows worked successfully for multiple users yesterday. Today, all workflow tools connected to the agent began returning an immediate HTTP 403 authorization error. I did not intentionally change the agent, workflows, environment, or workflow permissions before the issue started. Error message: You don’t have permission to use this tool. You’re signed in, but access to this resource is blocked. Error details: Authorization - 403 Example error information: Status: Failed Error message: Flow returned HTTP 403 Error code: Http403 Inner error code: NotSpecified Tool duration: Approximately 93 milliseconds Configuration: - Copilot Studio new agent experience - Copilot Studio new Workflows experience - Agent and workflows are in the same Power Platform environment - Workflows use the "When an agent calls the workflow" trigger - Each workflow includes a "Respond to the agent" action - Workflows are saved and published - Agent is saved and published Observed behavior: The problem affects several independent workflows, including: - New-request submission - Current-user identity resolution - Approval decisions - Requester justification - Executive decisions - Fulfillment updates For every affected workflow: - The agent fills the workflow inputs correctly. - The tool call fails almost immediately. - No corresponding run appears in the workflow Activity history. - The workflow trigger is never reached. - No workflow actions execute. Because no workflow run is created, the rejection appears to occur before workflow execution, possibly within the Copilot Studio agent-to-workflow authorization or invocation layer. Troubleshooting already completed: - Confirmed that all workflows are published. - Confirmed that the agent is published. - Tested in a completely new conversation. - Removed an affected workflow tool from the agent. - Saved the agent. - Added the same published workflow back to the agent. - Reconfigured and verified the tool inputs. - Republished the agent. - Confirmed that no workflow Activity run is created. - Confirmed that the issue affects multiple workflows rather than one specific workflow. Removing and re-adding the workflow did not resolve the problem. Questions for the community: 1. Is anyone else currently experiencing HTTP 403 errors when Copilot Studio agents invoke workflows? 2. Is this a known issue or regression in the new Workflows experience? 3. Is there an environment-level or tenant-level permission that controls agent-to-workflow invocation? 4. Could a tenant policy, Conditional Access change, service principal, connection reference, or workflow-sharing configuration cause all workflow tools to fail simultaneously? 5. Where can an administrator find detailed authorization logs when the workflow never creates a run? 6. Has anyone found a workaround for this issue? Any guidance or confirmation from others experiencing the same behavior would be appreciated. I can provide screenshots, complete error details, timestamps, and additional configuration information if needed. Thank you.
