Given the sheer number of officials doing thing this, I can only assume this is done mostly out of ignorance about how email works. If I knew nothing about email, I could see myself assuming IT has a magic way to archive this. Remember when Sarah Palin's account got hacked? She probably never thought about how the security questions could easily be looked up once she was in the public spotlight. Once your email account is set up, I imagine most people don't really think about it. Of course, it's also 2014, there is no reason a high-level official should be this ignorance, but it wouldn't hurt for aides to make sure they are using the correct email account.
