Internal Meetings vs. External Meetings
External meetings are all meetings with users who are not part of the same organization as the meeting creator. If you are a Corporate user then these external meetings may or may not also include internal colleagues who are also in your Zoom.ai corporate account. For example - if you are a recruiter booking a meeting with a candidate (external) and the hiring manager (internal), or a sales rep booking a meeting with your client (external) and your sales engineer (internal).
Zoom.ai does NOT have access to external invitees calendar availability during meeting creation and therefore is not able to suggest overlapping availability for external invitees during meeting creation. Therefore Zoom.ai takes care of sending an invite to these invitees, invitees select a time that works for them, and then your assistant books the meeting based on the best time available (this is supported by Zoom.ai's intelligent group algorithm!) Zoom.ai does allow external users to upload their calendar (for a single private session) to make it easier for them to select a time that works for them.

Internal meetings happen when everyone (meeting creator + invitees) are Zoom.ai users. When that occurs - and because your assistant already knows when they're available - the meeting owner is able to select a mutual time that works for everyone. In this scenario the meeting can be booked right away. Invitees would be sent a meeting notification from Zoom.ai (via email or their preferred notification method as set in Zoom.ai) and a calendar invite. The meeting would be automatically added to all invitees calendars.
Alternatively a meeting creator can choose to let their internal colleagues decide by selecting "Let them decide" which will trigger the meeting invite flow - as seen here. In this scenario Zoom.ai takes care of sending an invite to these invitees, invitees select a time that works for them, and then your assistant books the meeting based on the best time available (this is supported by Zoom.ai's intelligent group algorithm!)
