BUG: I like Outlook.com's feature of posting to a friend's FB wall without logging on to FB. However I see a bug in the implementation. If the user has opted not to have other's WRITE on their wall it always throws the error message 'An error occured'.

What I expect? Actually it is Outlook.com's responsibility to hide the textbox 'Post to Wall' or at least make it grayed out with a tool tip that 'The user has not opted to be messaged through their wall'.

Technical Solution:
Outlook.com should check the can_post value in the FQL before the profile page is rendered. FQL reference is below: https://developers.facebook.com/docs/reference/fql/user/
