Using Classic Outlook on Windows for personal email, calendar, and contact management
Hey Hector,
The New Webinar options follow the meeting rules and limitations i.e
Scheduled Meetings/Webinars (Outlook/Teams calendar):
- 1,000 participants
- 20,000 View/Listen only participants
https://docs.microsoft.com/en-us/microsoftteams/limits-specifications-teams
See also the introduction text which mentions the same 1,000 limit:
For reference Live events cater for higher volume:
LIVE Events
- Audience size - 10,000
- Event duration 4 hours
- 15 concurrent live events per tenant
NOTE:
until June 30 2021, Microsoft have temporarily increased this to:
*Audience - 20,000*
50 events per tenant
*Event duration 16 hours*
Hope Helps
