Hello Kevin

Recurring appointments feature allows you to enable recurring for any service, but your customers get to choose whether the appointment they're booking will be a recurring one, or not.

What you can do is use events. There, you can define the maximum number of attendees, and set up when booking will start, and when it will end. 

Hello again Kevin

Did you connect your employee to his Zoom account? It sounds like you configured Zoom, if you can use it in Appointments (Services), so that's the only thing that comes to mind.

If that doesn't help, please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. 

You can write credentials here just check Private Reply so nobody can see them except us.

Hello Leon

Have you followed the instructions listed below?

If you can't resolve the issue, please open a private ticket, where you can share the log in credentials with us, and we'll gladly help.
