Which calendars does Fellix work with?
Google Calendar and Microsoft 365 / Outlook, synced both ways: busy times are blocked and bookings appear in seconds. Calendly bookings can arrive too.

Google Calendar and Microsoft 365 / Outlook. The sync runs both ways: events already in your calendar block those times, and bookings made through Fellix appear in your calendar within seconds. Bookings taken on Calendly can arrive in Fellix as appointments too.
Settings → Integrations: calendar connections.
