Teams offers a text chat/instant messaging feature and the process is simple:
Switch to the Chat section in the left-side navigation.
Click once on the contact of your choice to select the correct person. Note the colored circle at the bottom-right of the person’s avatar (or initials), located to the left of his/her name.
- Green: Available
- Yellow: Be Right Back/Appear Away
- Red: Busy/Do Not Disturb
Find and click in the chat text box at the bottom of the screen.
Type your message and press the Enter key on your keyboard. Wait for a reply and type in this same box. The text thread will appear in the main window.
