The maximum size of a regular Collaborate Ultra session is 250 users.

If you need to run a Collaborate session with more than 250 users (up to a maximum of 500 users), you will need to create the session as a Large Scale Session.

Having created your Collaborate event, go to the Session Settings tab.

Scroll down and tick the box under Large scale session (250+).

When you tick the box you’ll see that some options are automatically greyed out.

These functions are automatically disabled for participants in a Collaborate Large Event:

• Share Audio
• Share Video
• Post Chat Messages
• Write on Whiteboard or Files

A Large Event cannot be

• a recurring event
• open-ended.
• supported using AWS Chime option. For further details see the Blackboard support article Collaborate: About Chime
