We just upgraded from Outlook 2003 to 2010. We're using Exchange 2003. With Outlook 2003, our users were using a bunch of public folder calendars to manage booking appointments for therapists. They would color code each appointment, to signify something of importance.
Since migrating to Outlook 2010, those color codes are not consistent between users. One person may see red for an appointment, where another person may see blue.
What has changes between these versions and what might I do to fix this problem?
