Office Downloading Files Even Though Locally Synced through MacOS App
One thing our users have noticed is that in order to take advantage of the Co-Authoring ability, Word or Excel files need to be opened through File ➜ Open ➜ Dropbox (Beta) and navigating to the file. This causes Office to then display a "downloading" window and download the file even when it is already locally synced on the computer via the Desktop app. When users open up a document from the Finder, Co-Authoring is not available. Are there any plans to add the ability in the office plugin to detect when a file is already local and just open the file? Or to be able to add Co-Authoring from locally open documents? Most users have "muscle" memory to navigate to the file on their desktop/Finder and open from there vs the File➜Open menus in Office.
