The purpose of this survey is to understand how users of Outlook today use the Free/Busy feature to schedule meetings, and whether a Universal Free/Busy service for calendars - that works across different calendar servers, calendar clients, and firewalls and allows a user to see any subscriber's scheduled availability - would be appealing to end users as a productivity enhancer and acceptable to IT administrators. They will select one user at random to receive an Apple iPod mini as an incentive to participate.
