It refers to the Calendar folder of a mailbox.
The free/busy data is used extensively when scheduling meetings.
Outlook 2003 client
The Free/busy data is stored as messages in a dedicated system public folder. Each administrative group in the Exchange organization includes a Free/Busy folder.
Outlook 2007 client
When Exchange 2007 services OUTLOOK 2007, it does not use the public folder for OAB and free/busy data. Autodiscover service is automatically installed when Client Access Role is installed. The Autodiscover service helps Outlook 2007 locate various Web services, such as the Unified Messaging, Offline Address Book, and Availability services.
WHEN Outlook 2007 is configured with exchange 2003 mailbox user, it uses the public folder for OAB and free/busy data.
If you are providing external access to Microsoft Exchange by using Outlook Anywhere (formerly known as RPC over HTTP), and you want your Outlook 2007 clients to be automatically configured by using the Autodiscover service, you must install a valid Secure Sockets Layer (SSL) certificate on the Client Access server that includes both the common name (for example, mail.contoso.com) and a Subject Alternative Name for autodiscover.contoso.com.
