I don't really understand their bug description but the result is:

Current Status: The Office Apps team has temporarily disabled Dropbox integration in the service.

Looks like they really messed something up and now have huge problems fixing it.

Do I hear "OneDrive"? Or was that "DR-DOS"?

Don't mix up OneDrive and OneDrive for Business, those are two completely different products that don't have anything in common ;-P
