And the reality is that there's a vanishingly small percentage of that archived email that is of any use to you or anyone else. I don't have anything before about 2001 for reasons of isolated proprietary mail systems (e.g. minicomputer-based), disk failures, or just not making the effort to archive. I do have about the next 10 years saved but it's sitting in Outlook on a retired Windows system I keep around for such purposes--but there's no easy way AFAIK to translate it to another format and it's not something I'm inspired to devote great energy to.
