It only happened once at the moment, so I’ll wait until next time (and hope that it won’t happen again).
I’ll keep the reply-by-email trick, thanks. But does that mean that for an event every week for a whole year, we’ll have to generate 52 replies ? It will make the topic difficult to read…
Otherwise I suppose, as I have admin rights, that I can also use the API to add manually the appointments.
Thanks for the insights !
