Outlook calendar not importing categories (Mac)

Hello all, 

I have a work PC and a personal Mac which I prefer to use. I have my Mac's Outlook configured with my work account and get all my emails as well as the shared calendar that we rely on heavily with different categories. My problem is that the categories(and colors) don't import to my Mac's calendar. Every event shows up as red (Busy). Oddly enough my co worker's Mac works fine but I can't identify what the difference is. 

Any help is greatly appreciated! 

Thank you
