Do I need a special license to edit my Dropbox files in an Office Online application?
If you have a Dropbox Basic, Plus, or Family account, you won't need a Microsoft account or Office license to edit your files.
If you have a Dropbox team account, you'll need an enterprise Microsoft account with a license that allows editing in Office Online (Business, Business Premium, ProPlus, E3, E4, or E5).
Additionally, if you're using a tablet larger than 10", Microsoft requires that you have an O365 license to use Office applications.
