Users can’t add Copilot agents or bots to Teams chats – where should I look?

Question

Users can’t add Copilot agents or bots to Teams chats – where should I look?

StephanG 846

Hi everyone,

we are currently rolling out Copilot for everyone and came across this feature: https://support.microsoft.com/en-us/office/copilot-in-teams-chats-2c613de4-cd26-4ae3-9e4b-6905d745d991

But we ran into a situation where users could neither add agents/bots to Teams chats nor add them from the Copilot app, even though Copilot itself was available.

3rd party and custom is not allowed - everything von Microsoft is allowed. The Copilot App in Teams is allowed for everyone.
I could add a bot or agent from a group chat - but not Copilot or any other MS bot.

Where is a setting gone wrong?

BR

Has this been resolved? After refreshing and publishing my agents I no longer have the option to add my agents to group chats. It only lets me post the link so that some one can add the app for themselves and no longer provides the message to "add to teams chat"

The bot is/was preview and i needed to put my Teams into "Preview" Mode.

After that i could add the agent and it could also be used by "normal" users.

Hi Stephan, this is usually a Teams app policy scope issue (not a Copilot license issue).

Please check in this order: Teams admin center → Teams apps → Manage apps

Confirm Microsoft 365 Copilot and the specific Microsoft bot/agent apps are Allowed.

Teams admin center → Teams apps → Permission policies

Make sure affected users are assigned a policy that allows Microsoft apps.
Verify no stricter policy is overriding via group/user assignment.

Teams admin center → Teams apps → Setup policies

Confirm users are assigned the expected setup policy and Copilot app is available/pinned as intended.

Per-user policy check

Open an affected user and verify effective policies (permission/setup) are the same as a working user. Scope behavior
Test both 1:1 chat and group chat. Some apps support only certain scopes. Propagation + client test
Wait for policy propagation, then test in Teams Web (InPrivate) to rule out client cache. IF
tenant ID,
affected UPN(s),
chat type (1:1/group),
timestamp,
screenshots/error text.

That is typically needed to confirm backend rollout or policy-gating for your tenant.

Reference docs:

- Copilot in Teams chats (feature behavior): https://support.microsoft.com/en-us/office/copilot-in-teams-chats-2c613de4-cd26-4ae3-9e4b-6905d745d991
Manage apps in Teams admin center: https://learn.microsoft.com/microsoftteams/manage-apps
App permission policies: https://learn.microsoft.com/microsoftteams/app-permission-policies
App setup policies: https://learn.microsoft.com/microsoftteams/teams-app-setup-policies

I checked

lease check in this order: Teams admin center → Teams apps → Manage apps

We have all Microsoft Apps allowed by default - Copilot is allowed for everyone

Teams admin center → Teams apps → Permission policies

Does not exist anymore

Teams admin center → Teams apps → Setup policies

Not pinned but they (also myself) can install

Per-user policy check

All users are affected
Scope behavior

Test both 1:1 chat and group chat. Some apps support only certain scopes. Propagation + client test

Does not matter - but in the M365 app it is also not possible

Wait for policy propagation, then test in Teams Web (InPrivate) to rule out client cache. IF

We do not need a change in policy - I signed out of my Teams and signed in again, tried on web etc

Rest of data is not for public

Hi Stephan,

Thanks for the update — since you've verified policies and tested across clients with the same result, this is likely backend rollout/feature-gating for your tenant.

Opening the support ticket was the right move.

Share with Microsoft Support:

Tenant ID

Affected UPNs

Chat type (1:1 vs group)

Timestamps + screenshots

One more check: Teams admin center → Settings → Copilot — confirm Copilot features are enabled tenant-wide.

Please update here once support responds — it will help others with the same issue.

I opened the support ticket - but it reaaallly slow.
It's more than 12 days now - and the only thing they proposed was allowing custom apps?!

Sorry you’re facing this — that does sound frustrating. Suggesting custom apps doesn’t really fit your case, so this likely points to a backend/feature rollout issue. I’d recommend asking support to escalate and confirm tenant-level enablement.

Support now says that the Agent is a 3rd Party and "custom agent"?
I think i would find more forums posts about that if this is true.

@StephanG I am also experiencing the same issue. Did you manage to get this sorted?
