A Microsoft file hosting and synchronization service.
Hi Patrick, at home OneDrive is almost certainly signed in with a personal Microsoft account, or not signed in at all, rather than your work account. Click the cloud icon (check the ^ hidden icons arrow) > Settings > Account > Add an account, and sign in with your work email. A second folder called "OneDrive - [your company]" will appear in File Explorer. That's your work OneDrive.
If your team's shared files are in SharePoint or Teams rather than your own OneDrive, open that library in the browser and click Add shortcut to My files. It will then show up at home too. Happy to help further if useful.
