The first time you login to a MADEC computer you will need to go through a couple of simple steps to complete configuration:
1. After logging in you should be presented with this screen. Click "Get started".
2. The next screen will ask you to Sign In. Enter your MADEC Email address.
3. Finally, allow the device to keep you signed in by leaving the tick box checked and click 'OK'
After the first sign in, Microsoft Teams should open automatically each time you login and remain logged in.
