Google Calendar does a great job when it comes to scheduling meetings with members inside organization. Free/busy view allows you to see attendee availability and select a time that’s good for all. But what do you do when meeting involves one or more external attendees? With ScheduleOnce it’s possible to see availability of all attendees, both internal and external, across domains, in one simple free/busy interface. Meeting organizer then selects a time and schedules meeting. It’s that simple. For solution to work effectively it should be completely integrated into user’s messaging and calendaring environment. ScheduleOnce provides meeting scheduling solutions for organizations using Google Apps. “Our solutions extend Google Calendar to support cross-organizational scheduling and include private labeling and robust scheduling features. Since our solution isn’t a standalone app but an add-on to a calendaring and messaging platform, we were looking to integrate it with a platform that’s open and inviting for 3rd-party vendors. Google Apps was the natural choice,” stated Google Apps blog.
