A request was made to see the details of meeting when doing a FreeBusy lookup from Outlook to Notes. In Notes the user had granted "Everyone" access to read the details of meetings which would show Detailed information in the Calendar:
Granting Permissions to see Details in Calendar
Result of Freebusy lookup in Outlook with No meeting information being displayed.
This issue can not be resolved as the Freebusy Information needed to populate the Outlook FreeBusy Lookup response is not passed back from Domino

This is all that comes back; the data and times of available slots for meetings.
No other information will come back as there is no way to Authenticate the requestor in Domino.
This is one of the functional differences of the two systems
