I’m really not surprised at this.
I once knew a Retired NCO type that would print out a copy of every e-mail that he received that was “questionable” in ANY way. I asked him about that once and all he said was “experience” and that e-mails had been known to disappear before. Other than that he was one of the most closed-mouth men I have ever known.
When I first started working...way back in the 80’s, the old timers called that the “Pearl Harbor File”.
He did that based on experience ~

“WASHINGTON (AP) - Some of President Barack Obama’s political appointees, including the Cabinet secretary for the Health and Human Services Department, are using secret government email accounts “
A lot of people do that. I always kept what I called a ‘red file’. When I left the company it went with me.
