Can I co-author documents on desktop or mobile?

No, co-authoring does not work on Office documents accessed from your desktop, or from Office mobile. To co-author an Office Online file, two things must be true:

  • The Office file must have been accessed from dropbox.com
  • The file must be saved in a shared folder

Additionally, all others must access the Office files from dropbox.com as well. The co-authoring feature will not work if one user is accessing from dropbox.com, while the other is accessing from desktop or mobile.

People who access the Office file through a shared folder must visit dropbox.com and follow the steps outlined earlier in this article.

Who can use the co-authoring feature?

  • Dropbox Basic, Plus, Family and Professional: You need a Microsoft account to co-author their files online, but will not need an Office 365 license.
  • Dropbox Business: You need an enterprise Microsoft account, and a license that allows editing in Office Online.

What file types will co-authoring work with?

  • .xlsx
  • .docx
  • .pptx
