We have a shared calendar in our team, so we can all see dates of key meetings, holidays etc.

I created most of the entries in the calendar (via GW8 on a Mac), and have 'categorised' them so different types of event are displayed in different colours.

Other users of the shared calendar don't see the categories or the colour-coding for any of the events - even if they've defined exactly the same categories and colours within their own client.

Do we just have to resign ourselves to a plain, black-and-white shared calendar?
