If your IT department installed these certificates they will show up under intermediate. I also work in a company where I need the certificates to sync my mail. If you're planning to move from from one ROM to another ther is no way to back up the certificates. Once they are installed you can't retrieve them. The Root certificates are those that come with the phone and every time you flash they will be there. What I did was when I went to IT dept. I told them to just leave them in my storage card this way when I flash to a new ROM all I do is just install from the memory card and is done no need to copy or paste no where and the certificate will always stay on the memory card unless you manually deleted.

I hope this helps.
