An attendee is a person who is not the organizer of the meeting but who attends the meeting.

When a meeting is scheduled by an organizer, attendees from inside and/or from outside the organization (Visitors) are invited to the meeting. The details about people attending a meeting are stored in the Attendees business object.

Registering attendees enables you to store the information related to a visitor or a person's details in other systems (such as Outlook).

This kind of information/data can be used for reporting purposes. For example, to track persons that attend a meeting, to be able to view all meetings attended by a person in the apps, etc.
