Before a meeting
To invite someone to join a meeting, employ the Invite people box to search for and invite people once you schedule or edit a meeting. Then, you can apply the scheduling assistant to view times whilst everyone is free.
In a meeting
Once you’re in a meeting, press Show participants in your meeting controls to see the people who were invited but haven’t joined yet.
To ask someone who was invited to join the meeting, pick their name > More options > Ask to join .
You can even enter a person’s name or phone number in the search box to append someone who was not formerly invited.
