How can guests RSVP "no" or "not attending" to my invitation?

STEP BY STEP INSTRUCTIONS

1. To enable guests to respond yes or no to event invitations, go to Setup > Registration.

2. Under Additional Setting, check the box next to "My attendees may RSVP no/not attending" and click Update.

3. To Save, click Update Settings

4. Now, guests will first respond Yes or No to your event, then they will complete the registration/RSVP form.

This setting helps you track who’s not attending just as easily as who is—keeping your guest list accurate and up to date.
