Recurring Zoom Webinar Still Appears in Attendees’ Calendars After Deletion

[Korlan]

Hello Zoom Support,

I’m experiencing a persistent issue related to a recurring Zoom webinar that I created a couple of weeks ago. Here’s the full context:

1. I originally created a recurring Zoom webinar via the Zoom web platform and added one panelist.

2. I did not send invites through Zoom, but instead created a separate calendar event in Google Calendar for all participants. I added the Zoom link there manually and sent out the invites via Google Calendar.

3. After some time, I needed to cancel and change the topic, so I went to Zoom and deleted the webinar entirely from the Zoom dashboard.

4. I also went to Google Calendar and deleted the full recurring series of events by choosing “All Events.” The event shows as deleted on my end.

5. However, participants are still seeing the event in their calendars — including the panelist, and others who received the original calendar invite.

6. In some cases, it even shows Panelist as the organizer now, even though I was the original host. I’m concerned this may be due to how calendar ownership behaves after a deletion.

I’ve tried all of the following:

• Deleting the event series entirely from Google Calendar

• Removing myself as organizer

• Confirming that the Zoom event no longer exists in my Zoom dashboard or trash

• Asking the participants to manually delete the event — but some are still confused because the event keeps showing up

What I need help with:

1. Is there a way to forcefully remove this Zoom event from all attendees’ calendars, especially those who received it via Google Calendar?

2. Why does the calendar event still persist even though it’s fully deleted from Zoom?

3. Can Zoom forcefully revoke this meeting link or ID across calendars?

4. Is there any setting or practice I should follow in the future to prevent this behavior when canceling or rescheduling webinars?
