Almost every folder in Outlook's mail windows is gray. I can still select them and see the content, but folders are gray, not black, so they are harder to read. The only folder that are black are;

Inbox

Drafts

Sent Items

deleted Items

Junk E-mail

(the two folder inside of Junk, my Exchange account name and On My Computer)

All of my exchange folders, my local folders, and my Smart folders are gray.

Any ideas? What does it mean that they are gray?
