Daily repeated events produce infinite copies of themselves
Recently I have set up some meetings in my Microsoft365 calendar, using evolution with evolution-ews. Two of these meetings for some reason created many (1000 each day) copies of themselves at the same time/date. Each of these copies is repeated daily (i.e. I have over 5,000 appointments, each of which recurs).
I cannot delete them fast enough, and have had to give up using my Microsoft365 calendar.
I cannot debug anything, because if I try to connect to that calendar, evolution (and firefox and my Android calendar OneCalendar) all freeze up.
