As the contracted e mail archiver there has to be ‘by law’ a paper copy of the e mails that Sonasoft was responsible for in that time frame....because they were being paid to do the e mail protection. If they did not do it....that has nothing to do with what they should have done.
No, you are wrong again.
The IRS was leasing software from them. That was their only responsibility, to provide software. The IRS retained the legal obligation to retain paper copies of documents.
And the contract was only for the IRS Office of Chief Counsel, not the department where Lois Lerner worked.
