I have a folder that I shared over the years that I would like to UNshare, but don't want the other person to know, or, at the very least, be sent an email informing them they are no longer authorized to access the shared Dropbox folder. Case in point, I have a folder I created for a client where the two partners both had access but now one has been bought out in the aftermath of a big hairy battle. I really need to remove the former partner. My question is, Will persons I "unshare" with be notified by email or pop-up notification that they are no longer linked to a folder, or does Dropbox simply make that space available to their quota and nothing is ever said?
