Somehow my ex-bosses calendar entries are now appearing on my Zoom account. I have no syncing of calendars enabled, yet yesterday and today I have seen her events start showing up.
Now that's a Zoom meeting I'd like to attend! 😉 Did you ever have permission to schedule meetings as this user? If so, it's likely you are seeing their meetings as a result. You may need them to remove this access to stop this from occurring.
