Additional features, settings, or issues not covered by specific Microsoft Teams categories
Dear @N Madhan,
Good day! Welcome to Microsoft Q&A forum!
Based on your description, I understand that your Copilot Agent in Microsoft Teams intermittently fails to return a response. You’ve built a basic chatbot that routes unknown intents to a backend via an HTTPS node in Copilot Studio, and while it generally works as expected, some user queries in Teams result in a blank response even though the query is received by Copilot. When the same query is repeated, the agent responds successfully on the second attempt.
Because this situation involves intermittent blank responses occurring specifically within Microsoft Teams, even though the Copilot Agent and backend are receiving the user query, the best way to move forward is to raise a support ticket through your IT Admin/Global Admin.
Your Global Admin can raise the support request via the Microsoft 365 Admin Center on your behalf and provide tenant‑level details that are required for investigation. This will allow the Microsoft product team to properly analyze the issue and advise on a permanent resolution.
For more details, you could refer to this article: Get support for Microsoft 365 for business
I appreciate your patience and the effort you’ve already put into isolating the issue.
Thank you for your kindness and understanding!
