Using a zoom meeting from a cancelled Outlook event scheduled with a Zoom meeting?

I have created an calendar invitation in Outlook and added a zoom meeting using the integrated functionality combining Outlook and Zoom. My question is if it is possible to cancel the calendar invitation but still use the zoom link for a meeting the same time? 

I cannot find the Zoom meeting in my Zoom app which makes me worried. Is it possible to find zoom meetings in the app that I have scheduled via Outlook?
Thanks
