Summary

Internet Free/Busy (IFB) is a feature of Microsoft Outlook that allows you to see when others are free or busy so that you can efficiently schedule meetings. Outlook users have the option to publish their free/busy information to a user-specified Uniform Resource Locator (URL) file server. You can share this URL file server with all users or limit it to a specific set of users.

An Internet Engineering Task Force (IETF) standard called iCal, is the basis for IFB. IFB uses a part of the iCal standard called iCalendar, an emerging standard for the format and storage of schedule information. iCalendar defines a structure for representing free/busy information in a standardized way.
