I'm using iCal for managing my schedules in my company. And my company is using Microsoft Exchange server for schedules. When I added the company account to iCal, it set the calendar color as orange. I have been using blue for my working schedule. So it's confusing me so much!
Usually, other accounts support changing the color by clicking Get Info menu. But this Exchange account doesn't show any configurable options. How can I change the color?
