Difficult to answer without confusing. "Classified" denotes different levels of damage to national interest that would occur should particular information be released (compromised). Levels of classification include, Confidential, Secret, Top Secret, and beyond. The nature of the information makes it classified. Level of classification is determined by an Original Classification Authority (OCA).
The Secretary of State is an Original Classification Authority. Every piece of information the Secretary of State deals with is considered classified until it is formally designated; Unclassified, Confidential, Secret, Top Secret, or beyond. That is why the Secretary of State is required to use only government secured communications systems.
In Hillary Clinton's case she set up an illegal unsecured electronic communications systems in violation of federal law. Every piece of information processed by that system was by definition compromised. This included e-mails that had already been formally classified but extracted, and raw information that was by its content classified.
Compromising this information alone, and it was all compromised, requires prison. Because it was willfully done by Hillary Clinton and her minions it is prima facie evidence of treason.
Make no mistake, Hillary and her minions knew exactly what they were doing. They knowingly and willfully compromised classified information. They are all traitors!
Apologies. Previous post gave the background. Answer to the question is that the e-mails were either restored to the original classification or were finally initially classified.
