Sure. If that info wasn't deemed classified at the time of sending I don't see how not. I gave you the link. A link that I in turn got from actually using the footnotes.
Three of them were sent either to or from an address called 'BBB Backup,' which one email identifies as a backup of a Blackberry Bold 9700, presumably belonging to Abedin.
Maybe the backup was stored to the same cloud address, maybe the computer was originally from Abedin and her husband took it over, maybe the tooth fairy intervened. I don't know. The point is if you want to charge Abedin (not Clinton considering she wasn't involved) the government would have to show that she PURPOSEFULLY planned to send her husband classified information. I would say good luck.

To your last link I say this. What does that have to with anything? Sure, there are rules when handing classified information. The question is what happens when you break those rules. You seem to imply that breaking them automatically causes criminal prosecution for everybody except for people like Clinton and Biden. This is simply not the case.

As such, the classification system exists in parallel to separate criminal penalties Congress has imposed to protect secret information deemed particularly critical to national security. Classified Information: Definition, Examples, and Laws.

I can go on and on and give you people even in the Trump era, some who I my opinion egregiously violated the espionage act and weren't prosecuted.
Since we are interested in applying the law to all people equally.
