Hi there,
I am using my icloud calendar for family stuff.
For this I usually send an invite from my office outlook to my iphone and add the entry to the icloud calandar.
Usually it works well,but some old entries are not deleted (and not visible in the online iCloud calendar).
How can I delete old entries which only exist in HA?
I found the culprit:
The zombie entries came from rejected invites.
These still were in the HA calendar, but not shown in the web (icloud.com).
I just needed to send a cancellation of this very calendar entry to my private email and update the entry accordingly.
Voilá - it’s gone.
