[SOLVED] "User already exist in your org" I can't create a new email account!

[SOLVED] "User already exist in your org" I can't create a new email account!

I've checked on "Groups" and've tried to add as "Secondary email adress", it is nowhere to be seen! When I try to add as Second. email, this message appears "email account already exists" (in portuguese). When I try to "Add user", it shows the message "User already exists in your org" (in english).

The email account I want to add is contato@roupadequintal.com.br

Any help?
