Syncing with Dropbox

I share a database with an employee. Using the DevonThink sync I synced my database using Dropbox. I bought my employee a license and in attempting to sync my database he does not appear to have access to the Dropbox sync packet.

Dropbox says I can only share this through a link, which means uploading and downloading every time we make a change. It appears that he would have to be signed into Dropbox as me in order to make this work.

With Box, I was able to share the folder and he could sync to my database without signing in as me.

Is this not possible with Dropbox?

No, this is not possible with Dropbox.
