White events in Outlook 2011 for Mac

Hello,

I'm using my Exchange account to handle my events on Outlook for Mac 2011.

I can't figure out why some of my events turned onto white events : some of my categorized events turned into events with no colors at all.

I've purged caches (even the font cache), preferences files, desinstall/reinstall Office 2011.

Recreated and rebuilded identities.

But i can't turn back Outlook 2011 to a normal behaviour.

I need help, thank you.

P.S. : when i'm log into my Mac OS X Guest account, my Exchange events are allright.

Changing the busy state to free state then busy back again doesn't work.
