Setting up future meetings with participants using Teams calendar or Outlook integration
A Teams webinar can host up to 1,000 fully interactive attendees when the organizer has an eligible Teams license assigned; the exact subscription assigned to the organizer is the key detail needed to confirm eligibility.^1^
Licenses that qualify
The organizer is covered for a 1,000-attendee webinar if assigned one of these eligible licenses:
- Microsoft 365 Business Basic, Business Standard, or Business Premium
- Microsoft 365 F1 or F3
- Office 365 F3
- Office 365 E1, E3, or E5
- Microsoft 365 E3, E5, or E7
- Qualifying Education subscriptions
- Microsoft Teams Essentials, Exploratory, or Trial
- Teams Premium Legacy
These licenses provide either foundational or advanced Teams event capabilities. Both categories support events with registration and full engagement—microphone, camera, chat, reactions, raised hands, polls, and Q&A—for up to 1,000 attendees.^1^
What to check
- Ask your Microsoft 365 administrator for the exact license name assigned to the webinar organizer. The organization’s general subscription is not enough if that license has not been assigned to the organizer.
- In Teams, open Calendar, select the webinar, and choose Registration > Configuration.
- Set Event capacity to 1,000. This controls how many people can register; it does not increase the organizer’s licensed limit.^2^
- If the 1,000 option is unavailable or registration controls are missing, contact your IT administrator to check the organizer’s assigned license and Teams event policies.
For a definitive check, provide your administrator with:
- The exact Microsoft 365 or Teams license assigned to the organizer
- Confirmation that the event is a webinar, not an ordinary meeting or town hall
- The event capacity currently shown under Registration > Configuration
- Any warning displayed when capacity is set to 1,000
- Whether Teams Premium was purchased before April 1, 2026, if relying on legacy Premium event capabilities
The 1,000 figure is the attendance ceiling, not a guarantee that all 1,000 registrants will attend. If exactly 1,000 attendees are required, account for no-shows separately when planning registration.
