My account shows that someone else is the owner.

Hi there, Leacato, welcome to our Community! 

Usually the owner of Dropbox account is the person that is associated with the email address linked to said Dropbox account. 

So, if you find the email cat@dropbox.com in my account settings, but I don't have access to that address, then technically the person that owns the email address, can also be considered the owner of the account. 

Is that what you're talking about, or are you referring to shared content, and the owner there?

If so, then the only person that would be able to change/remove that would be the owner of said shared folder. 

If you wish, you can copy the content of the shared folder, and re-create an identical but new folder, that you can then share with the people you want. 

I hope this helps!

This has happened to my account, too!  One day, I noticed that the "owner of my paid Dropbox account is someone I thought I didn't know at all, but then realized was once one of clients, for a small and very brief case.  I have had - and paid for - my dropbox account since long before that person was a client, which at this point was a couple of years ago.  ????????!!!!!!!  This is more than a little alarming; I can't share personal information about my cases, my clients, if some stranger has somehow gotten the rights to my account! When I wrote to Dropbox support, I got a bottled response, showing that the respondent had not even read my email.  This is about as critical as it gets for a file storage company.

HELP

Hey Duke of Whirl - sorry to hear about this. 

Since you've already contacted our support team about this, could you let us know your ticket ID so that we can look it up in our system too?
