"The agent isn't available in Word, but you can access it in Microsoft 365 Copilot Chat."

Question

"The agent isn't available in Word, but you can access it in Microsoft 365 Copilot Chat."

Daniel A Bell 0

I've created a custom agent in Copilot Studio. Published it to the Teams + Microsoft 365 Copilot channel. While the agent appears in Teams and Microsoft 365 Copilot Chat, it is greyed out in Word. The message displayed says:

"The agent isn't available in Word, but you can access it in Microsoft 365 Copilot Chat."

Steps I've taken:

Published the agent to the Teams + Microsoft 365 Copilot channel.
Verified my subscription (Monthly Office 365 Suite).
Checked the burger menu in Word's Copilot panel, but the agent is not listed alongside others like Prompt Coach, Writing Coach, etc.

I watched the video Microsoft Copilot Studio Demo (timestamp: 7:47 onwards) and followed the steps shown, but I still cannot access the agent in Word. Notably, my channel is named Teams + Microsoft 365 Copilot, whereas the channel in the video is named Teams + Microsoft 365.

Could this discrepancy in channel names indicate a difference in functionality or permissions?

Solution: Make the custom agent but via Microsoft 365 Copilot desktop app, not via Copilot Studio on browser.

We are facing similar issue. According to this message center link General Availability of Declarative Agents in Microsoft Word and Microsoft PowerPoint (Web) - M365 Admin and this article m365copilot-docs/docs/declarative-agent-document-interaction.md at main · MicrosoftDocs/m365copilot-docs · GitHub and from this video Build Your Own Custom Copilot Agent for Word | Full Walkthrough + Real Use Case Agents created in COpiulot studio should work within office apps like word. But they doesn't seem to work. Is there any additional configuration required.

I had to use Microsoft 365 Copilot desktop app, not Copilot Studio via browser; in order to get the agent to work in Word

Thank you @Daniel A Bell for the suggestion. I was able to get a agent created using Copilot Agent Builder(withing Copilot) to work inside Word. However the insert option from agents is not working. Also is there way to further extend the agent using Copilot Studio.

I'm actually up to the point where you are at now. Note: interaction with indexed SharePoint only works on Word Online and not Word local, even for the exact same agent

I was able to get agents created in Copilot Studio work within office apps using the steps provided here https://microsoft.github.io/TechExcel-Extending-Copilot-for-Microsoft365/docs/Ex02/0202.html however insert and selection are still not working within the agent
