How do I disconnect my outlook calendar from zoom??

Recently,  everything I put in my Outlook Calendar shows up in Zoom as a meeting and even changes my online status to "in a calendar event".  This are random tasks or reminders I put I my calendar... not zoom meetings.

I have no idea how this got turned on, and can't find a solution to turn it off!  I just have a basic free account, and have not added the upgrade to Calendar/mail integration.   I use the zoom app to chat with my team and book zoom meetings.  I do not want zoom to read my outlook calendar. 

When I logged onto the support page, all these "notifications" popped up that seem to be related maybe? (can't attached the screenshot, so typing out below)

"Adding Role sn_esm_user to ***********"
"Adding Role Task_activity_reader to ***********""

"Adding Role sn_apptmnt_booking_appointment_booking_user to ***********"

"Primary email device created for MyFirstname Lastname"
