We have a department that wants to have different color coded categories for their department to use on calendar entries (appointments) on a public folder calendar. They want to have it set up with some type of master category list (MCL). So that when one user enters an appointment that has a certain labeled color all the other users that access the public folder calendar will see that entry in that color. We use Outlook 2010 and Exchange Server 2010. We are looking for options for them to consider from automating the process to end user directions for setting up this process. We are interested to know what the experts think.
