Hi @Apollo services
The participant capacity limits for Microsoft Teams meetings and webinars depend on your subscription plan:
- With Microsoft 365 Business Basic, Microsoft 365 Business Standard, Microsoft 365 Business Premium, Microsoft Teams Essentials, and Microsoft 365 A1 plans, you can host online meetings and video calls for up to 300 people using Microsoft Teams.
- With Microsoft 365 F1/F3/E3/E5/A3/A5/G3/G5, Office 365 E1/E3/E5/A3/A5/G1/G3/G5, and Microsoft Teams EEA plans, this limit increases up to 1,000 people.
As for whether Microsoft provides an API to retrieve the participant capacity limit of a Microsoft Teams meeting or webinar based on the current subscription plan, this is beyond our support scope. Thanks for your understanding and patience.
The following table provides a list of APIs available across the Microsoft Teams JavaScript library and Microsoft Bot Framework SDKs:
