I have a problem. I use Office Outlook 2007 as my calendar at work. I have several calendar names but the default one 'Calendar' i use as a personal one. Now i need to delete this calendar as my colleagues can read my personal appointments, etc. I want to put my calendar 'work' in it's place. Now i can delete all the calendars except 'calendar'. What can i do? Any ideas? I'm even open to the idea of wiping the whole of Office Outlook.
