We have a SBS 2003 server with about 10 clients connected to it. Our CEO uses a MacBook (Leopard) and we just convinced him to switch to Entourage/Exchange rather than using his MobileMe account. He had several calendars in iCal that we imported to Exchange and assigned to categories(based on the iCal calendar they were in). His assistant is connected to his Calendar using Outlook 2007. She cannot see any of his categories. I understand this is normal behaviour, but is there any workaround we can use? Some add-on tool that will sync the categories?
