When using Microsoft Office online with Dropbox requires access to files and folders for seamless collaboration. However, there's a workaround if your user doesn't want to share their private Dropbox. You can download the file, make the changes offline, and then upload it again. The new file will replace the previous one on the web. By the way, if you're looking for free activation tools, you should definitely check out kms-activators-free.com. They have some great options! Hope this helps!
