Copilot Studio Agent Working Previously, Now Failing in Teams with Consent Prompt

Hi,

We are currently working on a Copilot Studio agent within our sandbox environment. The agent was functioning correctly in Microsoft Teams until 6 February 2026. However, after publishing the agent and attempting to add or update it in Teams, we began encountering an error message stating “Something went wrong” during the installation process.

The error says: “There was a problem reaching the app.”

Despite this, the agent was successfully added at one point, and the welcome message was displayed. However, when selecting any of the available options, a consent box appeared (THIS IS NEW AND WE DID NOT ADD/ENABLE THIS). After accepting the consent, the following error message was shown:

“Something went wrong. Please try again.”

Hi @Valantis,

We tried removing and re-adding the Agent to the channel and publishing, and there was no change.

It does not work within the web Teams version either. It gives the same errors.

It does not work within https://m365.cloud.microsoft/chat .

Hello,

confirming we are seeing this exact same issue in my org.

We published a Copilot Agent a few weeks back and have published multiple revisions. This worked until today when we started receiving the exact error. We have performed all steps referenced from the OP.

Could this be related to Issue ID CP1227436:

Some users’ Declarative Agents in Microsoft Copilot (Microsoft 365) aren't responding to prompts

Some users’ Declarative Agents in Microsoft Copilot (Microsoft 365) aren't responding to prompts

Issue ID: CP1229864
Affected services: Microsoft Copilot (Microsoft 365)
Status: Service degradation
Issue type: Incident
Start time: Feb 9, 2026, 2:00 AM EST

User impact
Users’ Declarative Agents in Copilot aren't responding to prompts.

Scope of impact
Your organization is affected by this event, and some users of Declarative Agents are impacted. This information may be updated as our investigation continues.

Root cause
A portion of infrastructure responsible for Declarative Agents populating prompt responses isn't processing requests as efficiently as expected, producing an increase in latency and resulting in impact.

Current status
Feb 10, 2026, 2:39 PM EST
To ensure latency has returned to standard service levels, we’re continuing our extended monitoring to verify the issue is fully remediated.

Just wanted to follow up on this as the service appears to have been restored on the MSFT side of things.

I will say that I forced an update of the Teams desktop app this morning, however the issue was originally encountered in both the web and app version of Teams.

Perhaps related to the various CP related tickets referenced by MSFT Service Health over the past week or so.

CP1229864

Awaiting a true root cause from MSFT engineering.
