Additional meeting and call-related features and issues within Microsoft Teams for business
Dear Ali_215,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
The "Live" count refers to the number of participants who are currently in the meeting and actively engaged, while the "People" count includes all participants who have been invited to the meeting, including those who have not yet joined or have left the meeting. So, the "Live" count is a real-time count of the number of participants who are currently in the meeting, while the "People" count is a total count of all participants who have been invited to the meeting.
I hope this helps, please let me know if you need any further assistance from me. Please note that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. Thank you for your help.
