I am running Outlook for Mac on Office 365.  My computer is a new MacBook Pro (about 2-3 months old) running OS X Yosemite with all of the latest updates.  
I opened my Outlook calendar today and noticed that all of the categories and colors for my Exchange Server account disappeared. Does anyone know why that happened and if I can restore them?
