As the conector does not exceed the limit of 100 items, we are unable to retrieve all rooms in an Enterprise scenario. To be more specific, my customer is an enterpise consisting of 7.000 employees. Now we've build an app to book meeting rooms. Although we try to apply a filtered query on the full listing with the means to return a subset, only the first 100 items are consulted. The rest of the items are being ignored. So, if your item is listed past the 100 item limit, you are out of luck!
