Power Platform Community Forum Thread Details

When users send a message to the agent, they see the “typing” indicator, but after about 20 seconds it stops and no reply is sent. The end user then either has to send another message (which often does get a response) or wait around 5 minutes until the inactivity topic is triggered, which resets the chat automatically.

This was working perfectly fine for months until January 17th when it stopped billing. It works for some users sometimes, but generally doesn't work. It worked fine for hundreds of users for many months and now it suddenly stopped, though nothing has changed with the copilot or with billing or with SharePoint.

I saw another post on a different forum that didn't receive a resolution that had an almost identical issue that was post on Jan 17th (same day mine started failing)
Here's their post for more info:

Dear Microsoft Team,

I’m encountering multiple issues after deploying our Copilot Studio agent in Teams to approximately 400 users. The agent worked correctly for about 1.5 months, but for the past two weeks several users have experienced the following issue:

When they send a message to the agent, they see the “typing” indicator, but after about 20 seconds it stops and no reply is sent. The end user then either has to send another message (which often does get a response) or wait around 5 minutes until the inactivity topic is triggered, which resets the chat automatically.

The agent has been published to everyone in Teams (~400 users) and currently has about 10–20 conversations per day, though we expect this to increase in the near future.

Agent setup

Copilot Studio agent published to Teams and approved by admin
Knowledge sources: directly uploaded PDF files
No tools in use
General Knowledge turned off
Using the default GPT-4.1 model
Fallback topic not altered (only the message text)
Using PAYG
Authentication via 'Authenticate with Microsoft'

Troubleshooting steps attempted

Republished the agent
Switched the model to GPT-5 (this caused additional issues, including “AI limit” notifications for end users), so I reverted to GPT-4.1
Toggled General Knowledge on/off
Verified there are no topics with errors

I would appreciate any help or suggestions to resolve this, as it is currently harming user adoption of the Copilot Studio agent in Teams.

Thank you!
