Hello,
I haven't login my dropbox account (not this account asking the question, but the other account) for a long time, and when I try to login it requires the 6-digits code sent to my email address, however, my email address has expired, because I left my previous institute. So my situation can be summarized in the following:
1. email address linked to the account is not accessible, by no chance it can be recovered.
2. I have no device with the account login
3. I have the password for my dropbox account
What can I do to recover my account?
BTW, I am still paying for the professional plan!!
