Absolutely! If your instructor or classmates are logged into Teams, you will be able to instant message them. If they are offline, they will receive the message the next time they login. You can do 1:1 chat or group chats. To start a chat, click on the New Chat icon in the top menu bar (directly to the left of the Search bar) and begin typing the name of the person(s) you want to chat with. You can then type your message in the Message box at the bottom of the screen. For more information on chats in Microsoft Teams, please view Microsoft’s guide on starting chats and calls.
