Hi!
So, I did not use my old account for a long-long time now. The mail address does not exists enymore where the 6-digit code was sent.
The problem is, that the address was registered to a private domain. A couple of friends and me brought the domain back then, but it is not ours anymore. So the mail address cannot be recreated.
No device is connected to the Dropbox account.
Is there some possibility to change the address not logged in? Some support ticket maybe?
