Dropbox for Business now support coediting Office docs on the desktop
Back in November, Dropbox announced a partnership with Microsoft and developed the hooks so that users could edit Office documents within Dropbox (see Dropbox partners up with Microsoft). Today, Dropbox has taken the next step, and has released the first Project Harmony tools that extend that capability to the desktop. (I’ve written about Project Harmony before: see Dropbox Project Harmony is breaking the rules.)
When editing in Office apps, a Dropbox badge will appear:
This allows sharing of a link to the doc so that others can coedit.
When more than one author is working on a doc, the user will be warned about making changes, which will lead to the creation of a new document. When the other editor is done with changes, the user can opt to see that version of the doc, or their own.
Dropbox users will have to join the early access program to try these features. I guess I will sign up, too.
