Microsoft Office Online has edited, saved the file directly to the Box

Microsoft Office Online web-based office suite has started to support Box's storage service. Now you can access the Box website, order to open documents in Office Online, edit and then save directly to Box without re-uploading manually.

If you are an individual user, you can use the above feature for free, but if you are a business, you need an Office 365 plan . One drawback of the cooperation between Box and Microsoft is that you can only open documents from the Box and then switch to Office for editing. With Dropbox , it works both ways.
