Hi Stephen,
Glad to have you as a customer now 🙂
This doesn’t require configuration at all, just try to subscribe to the URL in your iCal (or other email software): webcal://your_site_url.com/events/ical . That should work! To test it be sure to create a couple of new events on your website.
If you think you need further assistance on this, please open up a new thread in the Events Calendar PRO forum. Someone in the support team will be happy to help you out. We try to keep this forum just for pre-sales questions.
Welcome on board,
Best,
Nico
