From the Stack Overflow for Teams app in the MS Teams directory, click the Install button.
You will then be prompted with a card to Log In to your Stack Overflow Team.
Once you Log in, authorize the integration between MS Teams and Stack Overflow.
Note: If your Stack Overflow Team uses Single Sign-on (SSO) for authentication, the first installation of the MS Teams integration has to be done in a browser, by an admin.
On the following screen, add the Team that you want to connect your MS Teams integration.
Once you do so, the Stack Overflow for Teams tab in MS Teams will confirm that you’re signed in, and ready to use the integration.
