Teams integration via Graph Api Limitations

Question

Hi we have a B2B SaaS app and we are looking to integrate microsoft Teams, we are planning to use graph API, our planned flow is :

• Authenticate User through Get access on behalf of a user - https://learn.microsoft.com/en-us/graph/auth-v2-user
• Get list of all users belonging to that particular organisation. through - https://learn.microsoft.com/en-us/graph/api/user-list?view=graph-rest-1.0&tabs=http
  -User can create Teams meeting and invite users from list of all users through - https://learn.microsoft.com/en-us/graph/api/application-post-onlinemeetings?view=graph-rest-1.0&tabs=http
  -Create calendar event for list of attendees of online Meeting through - https://learn.microsoft.com/en-us/graph/api/calendar-post-events?view=graph-rest-1.0&tabs=http
  -Fetch attendance Record after meeting ends through - https://learn.microsoft.com/en-us/graph/api/resources/meetingattendancereport?view=graph-rest-1.0

Problem we are facing is how do we identify about max duration Teams meeting can be set and max number of people user can invite to a meeting, of course this will depend on the user's organisation microsoft license, we are able to fetch user organisation license through - (https://learn.microsoft.com/en-us/graph/api/user-list-licensedetails?view=graph-rest-1.0&tabs=http), but how to we know about individual license maximum limitations? Is there an API which can tell how many user can attend online meeting and max duration? I guess max number of attendees that can be invited through a graph meeting is 1000 but what if that organisation license only supports 300 participants. It would really help if we could get some clarity regarding this issue.
Thanks

Hello @Srijan Singh

Thanks for reaching out!

The maximum number of people in Teams Meeting is 1000. You could find it from official document. Microsoft Teams Meetings have a Time limit of 30 hours. Refer this document.

Refer to this official MS documentation to know the max limit for number of people in meeting for various licenses. Please note that for the best experience in large meetings, webinars, and live events, Microsoft recommends using the latest version of Teams desktop client or Teams mobile clients. Also, note that Breakout rooms can only be created in meetings that have fewer than 300 attendees. In addition, creating breakout rooms in a meeting automatically limits the number of meeting attendees to 300. Please follow this document to know best practices for a large Teams meeting.

Hope this helps.
