unable to schedule meeting

I have been using Zoom regularly on my iMac desktop without issue. Today I tried to schedule a client meeting for tomorrow and Zoom automatically opened Outlook (which I NEVER use and do not have set up) and asks me to add an email. Prior to this, Zoom recognized that I was working from Apple Mail and everything proceeded with issues. I have put in a ticket but would love to solve this sooner than later. (And note that I am not a geek, so will not even try to start digging around to figure out why this has changed...)
