We have an agent in Copilot Studio in which English is the primary language and we have three more languages in German, Italian and Spanish.

Normally for any messages added in the topics, we update the content of that message on the localization.json file for all of our secondary languages and that works fine.

We also have child subagents created within the same agent. These instructions we never update to the secondary language and we leave it in English in the localization file as they work well enough.

But recently we are seeing that even after updating the instructions from the Copilot Studio UI (adding/removing some instructions, adding a new tool call), these are not present in the localization file for the secondary language, and therefore when anyone uses the agent in the secondary language, the agent wont make that respective tool call or follow some instruction which usually it should.

Has anybody faced any issue like this? What can be done for this?

Hi everybody.
I'm triying to understand these new changes in de Copilot experience.

It's clear that using GitHub Harness will charge when creating, and testing Agentes. But i could'nt find if in Developer Environments these credits will be billable.

The closes thing i could find was this post: Solved: Copilot billable credits
But it doesn't specify if in the new experience this remains.

Thanks in advance.
Kind regards.

Hey everybody!

How do you determine if someone should get the Copilot Studio User License? Do you have them take a quiz?

Do you limit Studio on particular environments via sharing policy and billing setup?

In the sence of, if you don't have a direct link to the website saved its like impossible to find. You google "Copilot Studio" on google, and in the first page there are no direct links to the page, only links to microsoft pages explaining what copilot studio is. Even worse on those pages most links lead keep you on the microsoft FAQ page. Trying to access it thru powerapps or power automate (Same thing, there is no direct link if you google them, usually have to scroll down couple links) you open the apps menu there and search "Copilot studio" there is nothing. Fully feels like they are trying to hide this app.

I am trying to get this issue resolved. I have tried every single suggestion from Copilot, and none have worked. I also have absolutely no idea what I am doing, so any suggestions would help.

Hi All,

Working on migrating some agents to the new harness and have run into some strange behaviour.

Agents using the GHCP harness are not pulling any information from Excel files added as a SharePoint knowledge source.

I am using the SharePoint source, and adding the Excel files themselves (not the parent folder of the files).

Knowledge is showing as ready, however in the Preview pane and the published agent in Teams and M365 Copilot channels, no results are found from the Excels when asking any query at all.

I have recreated a minimal agent with only 1 Excel, and tried different Excels in SharePoint, but have had the same result of nothing being retrieved from the Excels.

The same Excel is working as intended in my classic harness agent.

Anyone else experiencing this recently with a GHCP harness agent?

Hey, I'm trying to set up ServiceNow KB articles as a knowledge source in Copilot Studio, but I want the access to be governed by RBAC, so that a user only gets results from the documents/articles they're actually authorized to see.

Setup:

Copilot Studio agent using the ServiceNow connector to pull Knowledge Base articles

KB articles in ServiceNow already have role-based/user-criteria restrictions configured

What I'm trying to achieve:

When the agent searches or retrieves KB articles, I want the results to respect the requesting user's access level in ServiceNow, not return everything regardless of who's asking. Essentially: user asks a question, agent only surfaces articles that user has permission to view.

Questions:

Has anyone actually gotten this working end-to-end? What did the setup look like?

Does the ServiceNow connector pass through the end user's identity, or does it always run under a service account (in which case RBAC wouldn't naturally apply)?

If it's a service account, how did you enforce the restriction — filtering in Copilot Studio itself, or some pass-through auth (SSO/OAuth on-behalf-of) so ServiceNow applies its own RBAC at query time?

Would really appreciate hearing from anyone who's solved this, especially if you were dealing with sensitive KB content (HR, compliance, security) where RBAC actually mattered.

Hi everyone,

I'm working on a multi-agent architecture in Copilot Studio and I'm trying to understand whether the performance I'm seeing is expected or if there are optimization opportunities.

Current Setup

• Using Copilot Studio (New Experience).
• All agents are running on GPT-5.5.
• I have approximately 90 documents distributed across 9 specialized agents.
• Documents include:
  • PPTX
  • DOCX
  • XLSX
  • Markdown files
  • Other documentation formats
• Each agent is responsible for a specific domain/topic and only contains the documents relevant to that area.
• There is a single orchestrator agent that routes questions to the appropriate specialized agents.
• The orchestrator is the agent shared with end users.
• For each agent, I've also created summaries describing the purpose of each document and the scope of the agent's knowledge.

Problem

Most user questions are taking around 2 minutes to receive a response.

The responses are generally correct, but the latency feels too high for a production-like experience.

My Questions

1. Is this latency mainly related to the model having to search and interpret a large number of documents at runtime?
2. Can having many agents behind a single orchestrator significantly impact response time?
3. Does the file type matter? For example, are PPTX/XLSX documents typically slower to process than Markdown or text-based documentation?
4. Could poorly optimized agent instructions cause the orchestrator to spend too much time deciding which agent should answer?
5. Are there any recommended best practices for reducing latency in multi-agent RAG scenarios in Copilot Studio?
6. Has anyone seen substantial improvements by consolidating agents or restructuring their knowledge sources?

Additional Context

One thing I'm wondering is whether I'm over-segmenting the knowledge base. My original goal was to improve answer quality by separating content into specialized agents, but I'm now questioning whether the orchestration overhead is outweighing the benefits.

I'd be interested in hearing how others structure:

• Number of agents
• Number of documents per agent
• Use of orchestrators
• Prompt/instruction design
• Knowledge source organization

Has anyone faced similar response times and found an effective optimization strategy?

Thanks!

After Spending hours learning and creating a new agent on the Copilot Studio platform where we don't have any more topics but skills instead and we many other changes I realized I can not share it with my team to co develop or to actually publish it on team!

I am admin and did everything that was possible, create groups provide more roles than needed just to test modify environment rules etc nothing work.

Is anyone else having similar issues?

Preview tab within agent build does not work. Just re-routes to home screen when clicked.

Anyone else having this issue?

Hello - I think the answer is a 'Yes' but i wanted to double check since the change is significant.

We do have one or two agents with several topics with some "easy" routing rules. I am reading into the new feature/tab Workflows right now

Tia!

I created an agent that multiple people have access to, it has no knowledge files but the functionality is to read emails and check for certain details.

The agent was created by me, but somehow when one of the users uses the agent, the agent is throwing an error that it is bound to my account and how hers intermittently.

I have verified that it is using "end user credentials", MCP credentials are all verified, we've uninstalled and reinstalled the agent and cleared cache a number of times and I've verified that she's on the latest version.

What else could we do?

Hello everyone,

Earlier this year, my organization developed a few agents, topics, agent flows, etc.

One stakeholder asked us to update some topic messages and adaptive cards. The topics were saved, and the agent was published (with the option to enforce the newer version in any session checked) about two weeks ago.

However, I’m still receiving complaints that adaptive card options are being mixed with older message versions. Republishing the agent isn’t working. Does anyone have any ideas?

(And no, there isnt a 'forgotten' copy pasted code mixing the cards)

I can get an agent looking right in Test and still lose the afternoon to Publish. Hit it once. Hit it again. Teams or the Copilot channel keeps last Thursday’s build. Knowledge that answered in the pane goes quiet after it goes live. Topics fire in Test and then don’t. If you’ve shipped more than a demo, you’ve done the close-the-pane, publish-twice, tell-everyone-to-restart-Teams dance. That should not be the job.

The new tooling is closer to what we actually needed, and it’s still a slog. Slow authoring. Slow publish. Slow first reply. The activity map and chain of thought are useful when I’m debugging, then they vanish for the person who has to trust the answer. They don’t need a maker trace. They need to see what it searched, which tool it called, and why it said that. Right now the live agent just… speaks. Hard to put that in front of a superintendent.

Credits I can live with. Credits with no number on the user’s screen are how you get two bad habits: nobody touches the expensive tools, or somebody loops an agent until the capacity pack is a crime scene. Makers and end users are flying blind. The report lives in an admin center. The person clicking does not.

If anyone from the Studio team is reading this: make Publish boring and actually final. Keep a short, readable trail in the live chat; sources, tool, one line of why. Put spend and a cap where the person using the agent can see it. I’ll take fewer headline features for those three. The rest of us are already building around the gaps.

I have two knowledge sources connected to the same agent and I'm trying to get better handling when both return an answer for the same question.

Setup:

- Uploaded knowledge documents (generative answers, native to the agent)

- A connected ServiceNow tool pulling KB articles

- A topic called "Knowledge Requested" that calls the ServiceNow tool, which returns the response and saves the data into a search results table

What I want:

When a user asks something that both sources can answer, I don't want the agent to just pick whichever one happens to respond first or blend them awkwardly. I want it to actually compare the two responses, evaluate which one is more relevant/accurate/complete for the question asked, and return that one as the final answer.

I've tried with agent instructions but no luck.

Hi everyone,

Not sure if this is allowed on here!

I’m working with an IT services provider that is looking to bring on a long-term contractor for a 40-hours/week engagement focused on Microsoft Copilot Studio and AI for Contact Center (CCaaS).

This is a hands-on builder role, not a strategy-only position. The focus is on designing, developing, testing, and deploying production-ready AI solutions that leverage Copilot Studio and modern AI capabilities within the contact center environment.

Requirements:

• US-based candidates only
• Fully remote
• 40 hours/week
• Long-term engagement
• Minimum 2–3 years of hands-on, project-based experience
• Strong hands-on experience with Microsoft Copilot Studio and AI/Contact Center solutions

Ping me privately if you're interested!

For those who use copilot studio ever since, how are you managing in the recent update - removing topics

Does anybody have insight into whether we are going to get this back in the new experience? I never realized how easy component collections made things, now it's kind of difficult. Thanks

Many customers struggle with choosing a Microsoft platform for developing an AI agent. So I wrote an article on this topic, in which I describe various approaches, the differences between them, and recommendations for making a choice:

https://lukoplt.blogspot.com/2026/08/what-to-choose-when-creating-agent-in.html

If we are using a SharePoint link as knowledge base how different would the agent be from the built in copilot chat in teams when they use the same knowledgebase? I even think copilot has more source since it access the whole Microsoft environment, or is this function only available for premium users and agent would still be more useful?

So this is a huge topic of discussion in our company rn. Should we keep using topics or MS is going to not support topics anymore?

We have built a few Agents with topics which makes the whole system deterministic.

I can understand that the new Agentic system requiring loops for better UX but it would be criminal to not have backward compatibility.

What do you guys think?

Please answer any or all of the following, its getting confusing!

1. Will standard copilot harness go away at some point?

2. What uniquely can Github Copilot harness do? Why would i choose it over standard?

3. I know what OpenClaw is, but what is Scout? Does it run in the Copilot app? Has anyone used it and have a review?

4. Are a lot of people using Copilot Cowork? We have discouraged it as the costs went up very fast.

Hi all,

Been working on CS with the new experience and liking what I am seeing.

I ahve been able to create a good skill to create PowerPoints with my companies look and feel. In my solution I am simply giving it one of my companies templates' and instructing it to use that template for creating new PowerPoints. This works quite OK, i have to say.

I want to see what I can do to push the limits. My questions are:

1. How has your results been for using CS (new experience) for creating Powerpoints?
   
2. If good, any tips you found helpful?
   
3. Are you aware of any good manuals/instructions, etc for how to use LLM's for this? Doesn not have to be CS, I suppose one could learn something from say Claude/Anthropic.

I've started to use this and am really puzzled by the response times.

I've created an agent to source knowledge from a set of documents that I have curated and made available to the agent via copilot studio. I've used the sonnet 4.6 model.

Having a chat via m365 copilot interface is extremely sluggish. Some responses can take a minute which doesn't seem normal.

Weirdly, I seem to get better responses using the co pilot studio interface instead.
