Outlook freebusy information

How Outlook 2007 fetches Freebusy in Exchange 2007 environment:

Outlook 2007 runs against Availability Service Web Service and relies on the Autodiscover Service to find the Availability URL to view the Freebusy information on Exchange 2007. So in regards we can check the requests going to the CAS server. Outlook 2007 issues may be related to Autodiscover/Availability/CAS(IIS virual directories…speaking on larger scale. )
Information visible on OWA , not visible on Outlook 2007: Issue is more likely with Autodiscover.

Outlook versions earlier than Outlook 2007 uses LegacyExchangeDN attribute to view the freebusy information.
LegacyExchangeDN attribute is also used by Outlook clients’ in Exchange 2007 to delegate access to folders.
Outlook 2007 =>CAS local=>CAS Remote AG=>Ex2007
Outlook 2007=>CAS local=>Public Folder server by http://server/public/?Cmd=freebusy>

+CAS gets requests to get free/busy from remote AG user, CAS will choose home PF server as attendee’s home server. If there is no PF replica CAS will choose another PF randomly.
+If CAS can not return the information , it adds the server to badserver list and will connect to the good server for further information.
