Team owners can add anyone with an email address to your Team! Here's how:
1. Click the three horizontal dots next to your Team's name and select Add member. If you don't see Add Member, you will need to reach out to the Team owner to have them do these steps.
2. Invite anyone to your Team by entering their email address. Once you enter their address and click Add, they will receive an invitation via email to install the Teams app and login.
