gnus-icalendar - edit reply?

[Loris Bennett]

Hi,

I have gnus-icalendar set up with Org integration and everything works
fine. However, sometimes I would like to edit the reply when I, say,
decline an invitation and want to give a reason.

Does anyone know whether this is possible?

I have a vague recollection of having done it in the past, but maybe I
am just getting confused with the actual Exchange interface, which
fortunately I hardly have to use anymore, but which does offer this
option.

Cheers,

Loris
