When scheduling a meeting in Outlook the free/busy information for a delegate is displayed but the data is not correct and does not match the delegates calendar view.
This may be due to Outlook displaying cached information
Close Outlook. Click Start, Run and type
Outlook will start up and when sceduling a meeting will display new data returned by the WorkgroupShare free/busy server.
Note that private appointments will appear as busy periods on the free/busy display but these will not be visible on the shared view of this delegates calendar.
