I work from home but the company I work for uses Dropbox. I don't want to download or store this content on my personal/home computer but I want to be able to open files through Excel or Word etc. on my local drive so that I can easily make changes and have it saved straight back to Dropbox. A colleague is able to do this but when I try to open, all I get is "Excel for the web" or "Google docs". I have tried logging into Dropbox from Chrome and Edge with the same result. What am I missing?
