Published agent from Foundry doesn't work at all in Teams and M365 Copilot
I've switched to the new version of Azure AI Foundry (New) and created a project there. Within this project, I created an Agent and connected two custom MCP servers to it. The agent works correctly inside Foundry Playground and responds to all test queries as expected. My goal was to make this agent available for my organization in Microsoft Teams / Microsoft 365 Copilot, so I followed all the steps described in the official Microsoft documentation: https://learn.microsoft.com/en-us/azure/ai-foundry/agents/how-to/publish-copilot?view=foundry Issue description The first problems started at Step 8 (Publishing the agent). Organization scope publishing I published the agent using Organization scope. The agent appeared in Microsoft Admin Center in the list of agents. However, when an administrator from my organization attempted to approve it, the approval always failed with a generic error: “Sorry, something went wrong” No diagnostic information, error codes, or logs were provided. We tried recreating and republishing the agent multiple times, but the result was always the same. Shared scope publishing As a workaround, I published the agent using Shared scope. In this case, the agent finally appeared in Microsoft Teams and Microsoft 365 Copilot. I can now see the agent here: Microsoft Teams → Copilot Microsoft Teams → Applications → Manage applications However, this revealed the main issue. Main problem The published agent cannot complete any query in Teams, despite the fact that: The agent works perfectly in Foundry Playground The agent responds correctly to the same prompts before publishing In Teams, every query results in messages such as: “Sorry, something went wrong. Try to complete a query later.” Simplification test To exclude MCP or instruction-related issues, I performed the following: Disabled all MCP tools Removed all complex instructions Left only a minimal system prompt: “When the user types 123, return 456” I then republished the agent. The agent appeared in Teams again, but the behavior did not change — it does not respond at all. Permissions warning in Teams When I go to: Teams → Applications → Manage Applications → My agent → View details I see a red warning label: “Permissions needed. Ask your IT admin to add InfoConnect Agent to this team/chat/meeting.” This message is confusing because: The administrator has already added all required permissions All relevant permissions were granted in Microsoft Entra ID Admin consent was provided Because of this warning, I also cannot properly share the agent with my colleagues. Additional observation I have a similar agent configured in Copilot Studio: It shows the same permissions warning However, that agent still responds correctly in Teams It can also successfully call some MCP tools This suggests that the issue is specific to Azure AI Foundry agents, not to Teams or tenant-wide permissions in general. Steps already taken to resolve the issue Configured all required RBAC roles in Azure Portal according to: https://learn.microsoft.com/en-us/azure/ai-foundry/concepts/rbac-foundry?view=foundry-classic During publishing, an agent-bot application was automatically created. I added my account to this bot with the Azure AI User role I also assigned Azure AI User to: The project’s Managed Identity The project resource itself Verified all permissions related to AI agents publishing in: Microsoft Admin Center Microsoft Teams Admin Center Simplified and republished the agent multiple times Deleted the automatically created agent-bot and allowed Foundry to recreate it Created a new Foundry project, configured several simple agents, and published them — the same issue occurs Tried publishing with different models: gpt-4.1, o4-mini Manually configured permissions in: Microsoft Entra ID → App registrations / Enterprise applications → API permissions Added both Delegated and Application permissions and granted Admin consent Added myself and my colleagues as Azure AI User in: Foundry → Project → Project users Followed all steps mentioned in this related discussion: https://techcommunity.microsoft.com/discussions/azure-ai-foundry-discussions/unable-to-publish-foundry-agent-to-m365-copilot-or-teams/4481420 Questions How can I make a Foundry agent work correctly in Microsoft Teams? Why does the agent fail to process requests in Teams while working correctly in Foundry? What does the “Permissions needed” warning actually mean for Foundry agents? How can I properly share the agent with other users in my organization? Any guidance, diagnostics, or clarification on the correct publishing and permission model for Foundry agents in Teams would be greatly appreciated.
