Incorrect answer in Teams

Posted on by CU24111427-1

I have an agent in Copilot Studio. When I test it in the development environment, it answers my question correctly, retrieving the correct file from SharePoint. However, when I deploy this agent to a user in Microsoft Teams, that user reports that the same agent answers the question incorrectly, retrieving the answer from the wrong file. I've already published the agent, removed the channel, and recreated it. I've even asked the user to delete the agent from Teams and add it again, but nothing has worked. Does anyone have any ideas on how to resolve this?

Incorrect answer in Teams

Hi @CU24111427-1,

What you’re seeing is usually caused by the channel context and user permissions, not the agent logic itself.

A few things to check:
1.   Same environment & same version?
Make sure the Teams channel is pointing to the same environment (and same agent) you test in Copilot Studio. If there’s a copy of the agent in another environment, Teams might be using that one.

2.   User’s SharePoint permissions
In Teams, the agent runs with the end user’s permissions. If that user has different access than you (extra sites, fewer files, etc.), the knowledge search can pick a different file.

Ask the user to open the “wrong” file and confirm where it lives.

Compare their permissions and your own on both the “correct” and “wrong” files.

3.   Check the actual Teams conversation in Monitor
In Copilot Studio → your agent → Monitor → Conversations, open the session from that Teams user.

Expand the steps and see which knowledge source/file was used.

If the wrong library or site is being hit, tighten the knowledge source scope or its description so the planner prefers the right source.

4.   Disable any extra knowledge/web search
If web search or other knowledge sources are enabled, temporarily turn them off and test again so the agent can only answer from the intended SharePoint source.
Once you know which file/knowledge source Teams is actually using for that user, it’s usually a permissions or routing/description issue that you can correct.
