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?753Views1like13CommentsPower Automate Flows Created Outside Copilot Studio Not Appearing in Tools
Hello everyone, I'm facing an issue with Copilot Studio and would appreciate your advice. Context I have several Power Automate flows that I created directly from: https://make.powerautomate.com My goal is to use these flows as tools within a Copilot Studio agent. All components are in the same Power Platform environment. What I've verified The flows use the "When an agent calls a flow" trigger. The flows end with "Respond to the agent". The flows are saved and published. The agent and flows are added to the same Solution. The solution has been published. I am using the same account and environment for both Power Automate and Copilot Studio. The Issue Flows that are created directly from Copilot Studio appear correctly under: Tools Add Tool However, flows created from Power Automate (make.powerautomate.com) do not appear in the Tools list, even though they have the same trigger and response configuration. Question Are there additional requirements for a Power Automate flow to be discoverable by Copilot Studio? For example: Does the flow need to be an Agent Flow rather than a standard Cloud Flow? Are there known synchronization or caching issues between Power Automate and Copilot Studio? Is there a specific setting, solution configuration, or publishing step that I may have missed? Any guidance or experience with a similar issue would be greatly appreciated. Thank you!83Views0likes3CommentsMore powerful agents and workflows for autonomous business processes: Introducing a new harness for Copilot Studio
Over the past two months, weve been previewing a new capability within Copilot Studio that lets you build agents capable of taking on more complex business processes. Today, were excited to share that this capability is now generally available for production use and to introduce its new name: the GitHub Copilot harness in Copilot Studio. Meet the GitHub Copilot harness The GitHub Copilot harness gives Copilot Studio the coding and reasoning capabilities behind our most advanced agent experiences (like Copilot Cowork and the GitHub Copilot coding agent). This means your agents can now handle work that used to be out of reach, including processes that have many steps, many sources, and ambiguous decision points. The new harness is built for complex, long-horizon work using the latest frontier reasoning models like Opus 5, GPT-5.6 Sol, and Fable 5. It can plan, reason through dynamic problems, run an agentic loop, use skills, integrate workflows, connect to tools and agents in other platforms, and produce rich, multi-part outputs. In our own testing with real world business process evals, Copilot Studio shows significant performance and quality gains when using the GitHub Copilot harness. Improvements in multi-tool use, file analysis, code analysis, and knowledge quality mean these agents are more capable of taking on your most complex business processes. To help you build these more capable agents, were also delivering new experiences for makers building agents with the GitHub Copilot harness. The agent designer is more intuitive for authoring, putting the most important tools right within reach to make authoring faster, while retaining full agent lifecycle management features. Then, the workflow designer gives a visual canvas to understand and edit workflows, including adding agent nodes and running workflow evals. And soon, natural language authoring will let you describe your business goal and assemble the right combination of agents and workflows through a multi-turn conversation. Agents running on the GitHub Copilot harness use usage-based billing for all work, regardless of Microsoft 365 Copilot licensing. You pay for your agents usage based on the models you choose, the organizational context and tools you add, and runtime used. Certain AI-driven maker experiences, like natural language authoring, evaluations, and testing, will also fall under usage-based billing if building with the GitHub Copilot harness. You can learn more about Copilot Studio usage-based billing here. Continued Support for Copilot Chat and Standard harnesses Adding a new harness does not change the ones you already rely on. Different harnesses can be optimized for different outcomes, so rather than relying on a single one-size-fits-all approach, Copilot Studio now lets you choose the harness that best fits your scenario. This means Copilot Studio supports three harnesses today: The Copilot Chat harness, which uses the same harness as Microsoft 365 Copilot Chat and is ideal for customizing Copilot Chat experiences. The Standard harness, which most agents built in Copilot Studio use today and is great for conversational agents with rules-based topics. The new GitHub Copilot harness, which uses the power of GitHub Copilot SDK to automate complex, agentic business processes. We will continue to support the Copilot Chat and Standard harnesses in Copilot Studio for both existing agents and authoring of new agents. Microsoft 365 Copilot licensed users continue to benefit from fair use of Copilot Chat or Standard harness agents included in their Microsoft 365 Copilot license. For all other usage, the Copilot Chat and Standard harnesses will continue to be billed using the existing fixed rate card. Get started today The GitHub Copilot harness is generally available now, and you can start creating these agents directly from the Copilot Studio homepage. We cant wait to see what you build. Share your thoughts using the feedback control in the top right corner of the product. Your input directly shapes what we buildand howyoubuildnext. Try Copilot Studio today![]

Hi everyone, I'm investigating an issue with a Copilot Studio Standard Harness agent and would like to know whether others have encountered similar behavior. Scenario I have configured a tool in my agent using: Get file content using path The document is stored in my own OneDrive/SharePoint location and I have full access to it. This is not a chat file upload scenario and not a knowledge source indexing scenario. The agent is retrieving the document through a configured tool action. Behavior Observed Case 1 - Works The Word document contains approximately: ~4.1K words ~20 tables The agent successfully: Finds the file Retrieves the file Reads the content Generates a summary Case 2 - Fails I increase the document slightly: ~4.2K words More tables added The agent now returns a message similar to: The file was retrieved, but its content could not be converted to text. The response still indicates that: File found File retrieved Text extraction/conversion failed Important Observation Initially I thought this might be a word-count limitation, but additional testing suggests otherwise. I tested another document containing: More than 4.3K words Very few or no tables The agent processed that file successfully and generated a correct summary. Because of this, the issue appears to be related more to table-heavy DOCX content than to the total number of words. What Has Been Ruled Out The following do not appear to be the cause: File path issues Permissions/access issues File not found issues Connector authentication issues Large file size issues Chat file upload limitations Knowledge source indexing limitations The same tool and same retrieval approach continue working until the document becomes more table-heavy. Questions Has anyone experienced similar behavior with Get file content using path in Copilot Studio? Does Copilot Studio Standard Harness perform an internal DOCX-to-text conversion step after retrieving the file? Are there known limitations around processing Word documents that contain a large number of tables? Has anyone identified practical thresholds around table count, table complexity, or table-heavy technical documents? Is there a recommended workaround besides splitting the document into smaller files? Any insights, similar experiences, or Microsoft guidance would be greatly appreciated. Thanks!58Views0likes1CommentAgent 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![]

68Views0likes0CommentsUnanswered Questions on GitHub Copilot Harness in Copilot Studio
We're piloting the GitHub Copilot harness in Copilot Studio (GA August 2026) and several operational and architectural details remain undocumented in the GA FAQ, Microsoft Learn, or licensing guides. Looking for official answers or PM contacts on: Architecture & Execution When the harness breaks tasks into subtasks, does it use internal sub-agents or only skills/connected agents, what are the exact timeout/retry/max-execution-duration limits for long-running workflows, and are planning/context-retrieval/orchestration internals documented anywhere or is the orchestrator a black box? Model Selection Can individual skills within one agent use different models or is selection strictly agent-level, how are models chosen internally when multiple skills execute, are any internal models developer-configurable, and what's the roadmap for models being added/retired/deprecated plus the lag between public release and Copilot Studio availability? Cost & Token Optimization How exactly is the ~45% token reduction achieved, how much control do makers have over context/caching/retrieval/tool calls, what are per-model credit consumption characteristics, which models are most cost-effective for specific workloads, and what's the minimum credit cost for trivial interactions? Memory Management What are retention periods for session/working/agent memory beyond the documented 28-day user-memory expiry, is true long-term memory supported, and what changed versus earlier implementations? Knowledge Retrieval Can skills or system instructions influence retrieval strategy/document selection/prioritization/filtering, can planning stages perform conflict/duplicate/version detection before retrieval, and how does the harness decide which sources to search? Apps Feature What is the "Apps (preview)" capability for, when does it GA, and how does it differ from workflows/skills/adaptive cards/agents? Billing & Credit Sizing Is there a framework to classify users/agents by expected consumption and size credit allocation per group (citizen vs pro developers), and what's the minimum/typical consumption for simple/medium/heavy interactions? Governance & Admin Can usage limits be set at user level (not just environment/agent), is there an API/IaC path for large-scale credit assignment, can non-admins view their own consumption/remaining allocation, and is there a self-service request-more-credits dashboard? ALM & Environments What's the recommended path to move harness agents across Dev/Test/UAT/Prod (Solutions/ALM "setup differs" per parity charthow?), does GitHub integration replace or complement solution-based deployment, are there recommended AgentOps practices for source control/releases/versioning, and what baseline credits and onboarding model are suggested for citizen developers under usage billingany enterprise reference implementations?69Views0likes0CommentsAll 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 dont have permission to use this tool. Youre 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.137Views3likes3CommentsSnippet Files Truncating Data - Excel
Dear community, Background I am looking for feedback regarding a best practice for using Microsoft Excel files as a knowledge source. My data is structured in a tabular format, stored across 3-4 columns in Excel (~500 rows, one sheet). For context, it is a simple mapping file that can be used to query about team responsibilities and who to contact for a specific topic/region/etc. I use this file in parallel with Outlook and Teams tools to escalate topics directly to individuals. I have a skill already created (contacts-responsibilities) that very clearly details the file and how the Agent should behave. Issue In the "developer" preview, I can see the Agent is identifying the correct knowledge source, but the processing technique is resulting in truncated snippet files. After multiple fail-retry loops, the Agent concludes that the data is not present in the file (which it most certainly is). Here are some of the notes the Agent returns: "the snippet seems to be limited to a certain portion of the file" "the search result only returned partial data from the spreadsheet." Ask Any suggestions on what exactly to do here? I have read that issues should only occur when you hit 1500+ rows of data. I could split my data apart, but this would mean more maintenance on my side. Thank you! Any hint is appreciated.56Views0likes2Comments
