Change from iCal to Outlook calendar

Hello. I'll start first by saying I'm not good with technology, and even worse with technology troubleshooting. I'm recovering from a brain injury so things that may seem straightforward and easy to understand for you, may not be to me. I would appreciate patience in responses - thank you in advance.

I recently set up my Zoom account and it is syncing with my iCal; however, I want to switch this to work with my Outlook calendar. I need help figuring out how to do that.
