Abstract: To facilitate resource reservation, a server can preemptively determine resource availability. Indeed, upon receiving an availability request for a desired attendee for a calendar event, the request specifying a date and time, the server can transmit a search request to a server maintaining an organization resource cache, which stores availability information for resources. Upon receiving, from the server, a search result, and based on the search result, the server can store, in a memory, an indication of a specific resource that is available at the date and time.
