I have recently had to stop people from using the Box comment feature, as it was adding unnecessary tasks to my workflow, because it does not allow the author to respond to comments, and when i open a word document to edit, the comments disappear. Commenting feature needs to integrate with Office in order to be useful for reviewing MS office documents. As the author i 'must' be able to respond, and close comments, AND when i open the document for edit, i MUST be able to see the comments. The MS Office comment feature is fantastic and if Box is going to have one natively it needs to integrate with that, or be switched off for MS office documents.
