I have a user who, when given shared access to files in folders as View Only, was able to view the files in those folders for over a year without any problems. Now he can't access. When I checked in Dropbox on his status, his email address was still in the list of shared users for those folders, but it had DELETED in red listed next to it. ???? No changes at the Dropbox Admin end were made to cause this. So in an attempt to fix it, I went ahead and removed him. Now, when I try to add his email address back, I get the message "One or more names or email addresses you entered are invalid". But his email address is still a good one. Any idea what might be causing these issues?
