icloud and outlook 2010 calendar category color problem

Hello,

I have just started using icloud and have synced my calendar successfully with Outlook 2010. In Outlook I have calendar items differentiated with colored categories. When I open up an appointment, the correct color for the category is displayed, but on the mail calendar the color is different. I had included a picture with has a screenshot of the calendar on the month view where the color is light purple (not correct) for today 11/17. I then opened the appointment and color is dark purple (correct). If I make changes to the appointment, the color on the month view changes to the correct color, but the next time I open Outlook it reverts back the the wrong color.

Please help.

Best regards,

Jeremy
