1 Neige et Soleil sync option Hello, i don't have the option to sync with en url ics in my back office. How can i active it ? Thx 7 Isle of Wight … The option will be in there somewhere - depends on what your extranet setup is. I used to have Rates & Availability as one of the main icons in my extranet, but now I have Calendar, which has the calendar sync as a sub-page of that. If you find the calendar sync and set it up, don't rely on it. For many owners, the calendar sync is broken. Even if you reset it, it can change the settings on it's own and fail to sync with other OTAs. For us, this has led to several double bookings, which are a real pain to deal with. So if you use Booking.com calendar sync, always block manually in Booking.com and other OTAs every time you get a booking.
