Nope. There was no law against it.The mere existence of this non sanctioned or approved server is criminal.
It was stupid, it was careless, but it was not illegal.
Putting classified documents on it was illegal.
By even retaining any classified e-mails on that server she broke the law. 18 USC 1924 (a).
"(a)Whoever, being an officer… of the United States, and by virtue of his office… becomes possessed of documents or materials containing classified information of the United States, knowingly removes such documents or materials without authority and with the intent to retain such documents or materials at an unauthorized location shall be fined under this title or imprisoned for not more than one year, or both.
