Can Not Update a publish agente in Microsoft Teams

Posted on by Gabriel Mendizabal

We recently add and Published agent from Production environment in Microsoft Teams. Since the last update, we had to upload the manifest to the Microsoft Teams admin center in order to publish an agent. Now that it is pinned and published, we can't update to the latest version from Copilot Studio. Does anyone know why? I get an error.

Hi Gabriel,

Had you enabled the option Force newest version when publishing your agent?

Hi @Gabriel Mendizabal

Just to clarify: why wasn’t the agent published via the Teams + Microsoft 365 Copilot channel in Copilot Studio and then submitted through the admin approval process from there?

In my experience, that usually works without manually uploading a manifest.

Hi @Gabriel Mendizabal,

If you click Update now in Teams and get “An error occurred”, the most common cause is that Teams doesn’t reliably apply agent updates for users who already installed the app. The quickest fix is to remove and reinstall the agent:

In Teams - Apps, find the agent and Uninstall/Remove it

Reinstall it from Copilot Studio - Channels - Teams and Microsoft 365 Copilot - “See agent in Teams” (or the install link)

If it still looks unchanged, sign out/in or refresh Teams (Teams caching)

If the agent is admin-approved / in the org store, changes won’t roll out until you resubmit the updated version for admin approval and ensure the app is Allowed in Teams Admin Center.

If your update changed permissions, the update can fail if user consent is blocked by Entra/tenant policy your admin should verify consent/approval settings.

If needed, a supported “refresh” workaround is: disable/re-enable the app in Teams Admin Center, then toggle the Teams channel off/on in Copilot Studio, and republish.

let me know if that answers your question / Fix the problem.
