Additional meeting and call-related features and issues within Microsoft Teams for business
Dear David IPFD
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description, I understand you concern with Registration Capacity for Teams Webinar.
Microsoft Teams' maximum participant limits vary depending on the type of meeting and your Microsoft 365 plan. For Microsoft 365 Business Basic, Microsoft 365 Business Standard, Microsoft 365 Business Premium, and Microsoft 365 A1 plans, you can host online meetings and video calls for up to 300 people.
With Microsoft 365 E3/E5, Microsoft 365 A3/A5, and Microsoft 365 Government G3/G5 plans, this limit increases up to 1,000 people.
To increase your webinar capacity to 1000 attendees, you would need to upgrade to a higher-tier license such as Microsoft 365 E3, E5, A3, or A52. These licenses support up to 1000 interactive attendees and also offer additional features that might be beneficial for your webinars.
In the meanwhile, if you don't want to upgrade to a higher-tier license, as a workaround, you can use view-only mode in Teams.
While the interactive attendee limit for your license is 300, the view-only mode allows thousands more to join the webinar. These additional attendees can watch the webinar but won’t have interactive capabilities like speaking or participating in the chat. You can refer to View-only meeting experience - Microsoft Teams | Microsoft Learn.
If you have other questions, please feel free to let me know, I will continue to assist you.
Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!
