Copilot in Teams has its own chat and its own settings, unconnected to the Copilot checkbox in Word.

The settings that govern Teams itself are in the privacy guide.

How to find your Microsoft Teams AI opt-out manually

1. Open Copilot, then its chat settings

Copilot has its own icon in the left rail. Open it, then the three dots at the top right. The compose button sits next to them.

Step 1: the Copilot chat in Teams, with the Copilot icon in the left rail and the three dots at the top right

2. Set the three switches under Personalization

The dialog opens on General. Personalization is third, under Data controls.

Step 2: the Copilot chat settings dialog, showing the three switches on the Personalization tab

Custom instructions. Standing text attached to everything you ask.
Saved memories. Details kept between conversations. Manage saved memories beside it shows and clears what it holds.
Web search. Sends your question out to the web.

3. Check what you have shared, under Data controls

Two buttons, both about sharing.

Step 3: the Data controls tab, with its two Manage buttons and the Manage Access panel open

Manage Access. Prompts you created and shared. The link icon stops sharing one.
Shared links. Chats and responses you shared, and how to take them back.

Step 4: the Shared links panel, empty until you have shared a chat or a response

Both stay empty until you share something. A shared link keeps working until you revoke it.

What this gets you

Copilot stops keeping notes between chats and stops taking questions to the web. It still reads the chat you are in, and none of it touches training. On a work or school account an administrator can lock these switches.
