I have my working hours set from 08:00 to 17:00 and my calendar displays these times correctly. However, when i create a meeting and click on scheduling assistant the hours displayed are 08:00 to 16:00. I have tried the cleanfreebusy switch but no change. Does anyone know how to get the Schedule Assistant to display the correct working hours. I am using Outlook 2010 and we are on Exchange 2010 also.
