You can increase participants by hosting a large meeting or hosting a webinar instead of a meeting. Learn more about the differences between meeting and webinars.
Large Meeting is an optional add-on for Meetings plans that allows you to host up to 500 or 1000 participants depending on the license purchased. In large meetings, everyone can participate with audio, video, and screen sharing at their and the host's discretion. Learn more about purchasing and assigning large meeting licenses.
Webinars are used to host virtual events and broadcast them to up to 10,000 view-only attendees. This reduces risks of meeting disruptions and is a safer choice for large audiences of unfamiliar people, or people who are not as familiar with meeting controls who do not need to be on video or audio. Learn more about purchasing a webinar license.
If you want to invite fewer than 500 participants to a scheduled or instant meeting, you can do so without having to purchase the Large Meetings add-on or a webinar license. Learn more about inviting others to join a meeting.
