The new Teams Events Attendee Capacity Packs were introduced to support the April 1, 2026 Teams licensing changes, and mean that Teams Enterprise licensed users can run Town Hall events with more than the default 3,000 attendee limit.

Interestingly, these Capacity Pack licences are not assigned to a tenant, as you might expect, but to a meeting organiser. This does mean that if you inadvertently reassign a licence you might impact an upcoming event. To that end, there are new licence management capabilities added to the Teams Admin Center to hep admins discover, assign, and manage these licences.
