Existing Dropbox account was under a work email; shifted this across to personal email (needed to secure content immediately), with a view of opening a second account under the work email at a later date.
Am now at that later date, but Dropbox will not allow a new account using my name and work email, and defaults back to the existing personal account.
It shouldn't be that ****** to have two accounts under the one name, if using two different emails as login.
