This is completely missing the point though. She knows that her personal server is insecure, and doesn't need to know how it works to understand that. The point is that you don't send classified information over an insecure channel, allow non-cleared people access to a system/device that contains confidential information, and when found out, you most certainly go to extreme lengths to try and delete and cover up what you did. Read the recent FBI documents that were released. She repeatedly ignored security protocol and forced those people around her to allow her to do so. Whether or not she understands how Microsoft Exchange works is completely irrelevant.
