Invited participants: how to reschedule or cancel
When you invite someone to a specific time on your calendar, they become "invited."
This means they aren't yet confirmed, but if you want to have them pick a different time, simply cancel the invite and invite them to a different time. It's that simple. If you want to have them pick an entirely new time, either manually schedule them or use the invite previous feature to have them pick a new time.
Keep in mind, participants aren't confirmed until you confirm them or they click the confirm button in their invite email. Once that happens you would follow the steps to reschedule confirmed participants here. But for invited participants, here are the steps:
Step 1) Cancel the Invite
Open up the invited participant on your calendar, and then cancel that invite. Keep in mind they will receive a cancel email, so make sure to customize that from scheduling >> emails.
Step 2) Invite to a New Time
This assumes they chose multiple times in their original screener response, and you simply want to invite them to one of the other times they initially picked. If you want to have them pick an entirely new time, either manually schedule them or use the invite previous feature to have them pick a new time. After you cancel that invite, the first time turns red and says "invite cancelled" but more importantly that participant shows up in others times to be invited. That's it. Now the invited participant has essentially been rescheduled.
