If your instructor is using Microsoft Teams for a class, you will see your class listed by opening the Teams app or going to https://teams.microsoft.com. Then, click the Teams icon on the left app bar. You should have also received an email with an invitation link to the Teams Classroom. Once you find your class, click the General Channel to see Posts, Files, Class Notebook and more along the tabs at the top. You can chat with your instructor and classmates using the Conversation box in the bottom of the page.
