Amazon Chime currently supports up to 250 connections for a meeting scheduled or hosted by a user with Pro permissions.
Amazon Chime will send a note to an organizer that the scheduled meeting failed if there are more than 300 individual users invited to a meeting (distribution lists that are not expanded only count as a single user in this count).
There is a 300-item limit for the meeting roster which includes all users displayed under the Attendees, Invited, Left, Dropped and Declined sections.
If the roster reaches the 300-item limit, or there are 250 connections, new attendees trying to connect to the meeting are notified that the meeting is full and will not be able to join.
Please see the Amazon Chime pricing page. for more details about the various Amazon Chime permissions.
