The republicans need to dig into how the IRS uses Exchange-based email. Specifically, if they use Outlook as a client with cached mode. With cached mode (which is very common), the working copy of the inbox is on the local computer and a “shadow” copy is on the Exchange server. If you lost a hard drive, you would install a new one, re-install your software (Windows, Outlook, Office), then sign into Outlook with your email address. All of the email from the server would sync to the new client in the background. You could be up and running with a local copy of your inbox restored in a matter of a few hours, maybe even minutes.

It is not her official email that is needed; it is her unofficial ones like the EPA used.
I hate to say, nothing in going to happen but theater. I have a long history of watching Republicans fail.
Sad, but too true.
