I downloaded Office 365 onto my Mac (10.9.1), and was able to create my account. However, the screen looks like this, and I cannot access any mail at all.  I can drop down the menu items, but not click on anything in the inbox window itself - it looks completely empty.  

I really need this issue resolved for my job, since I work from home. Any help is appreciated!  

(And I have tried rebuilding my identity three times. Did not work)
