The meeting-reminder - popup-window offers options similar to “remind later again” and “do not remind again”.

all postpone-times that are beyond the actual meeting-start-time are shown in italic? reddish? with an “!” ?
____Update and Addition: how about adding some info in which calendar this event is stored?
for better understanding, I created this mockup…
