Use “Bookings from invites” in Recued. A calendar invite emailed to you for an appointment, a call booked through a link or tickets, becomes a booking with its time. An update moves it, a cancellation or your own decline cancels it. It starts when the invite arrives, not on a timer, and never answers an invite.

Use “Invites to your calendar” in Recued. A calendar invite emailed to you that is on none of your calendars is added to the one you choose, Recued's own by default. A later update moves it, a cancellation or your decline marks it cancelled. For mail whose provider adds no invites itself.

Use “Invites to answer” in Recued. A calendar invite still waiting for your answer becomes a commitment to answer it, due when the event starts. Your reply, sent from your mail, marks it done; a cancellation closes it; past the start it lapses. It starts when the email arrives, not on a timer, and never answers for you.

Use “Invite answers and cancellations” in Recued. When someone accepts, declines or says maybe to an invite you sent, or cancels one you received, you get a notification naming who, which event and when. It starts when that email arrives, not on a timer, and changes nothing.
