2012-10-22 12:43:09,090  INFO DominoFreeBusyConnector - email@example.com not found in Domino domain user list. Create new FreeBusyInfo instance. Mark user as invalid.
This is caused by using sub domains for email routing.
The targetaddress in Exchange is firstname.lastname@example.org
The internet address is Domino is email@example.com
In the Coexistence Manager for Notes Configuration Manager on the "Domino Free/Busy Settings" screen add a SMTP domain mapping where the "Exchange Forwarding Domain" is notes.domain.com and the "Notes Internet Domain" is domain.com.
The save and active the new configuration changes, and then try Free Busy again and verify the results.
