Even the US Congress thinks so...
California Rep. Henry Waxman, the chairman of the House Oversight and Government Reform Committee, briefly outlined the ongoing saga of the White House e-mails in his opening statement, noting that the Bush administration in 2002 effectively dismantled the Automatic Records Management (ARM) System instituted by the Clinton administration in 1994.Also of interest is David Gewirtz's update over at OutlookPower.
The White House "intentionally dismantled an effective system and replaced it with a primitive alternative that just didn't work," said Waxman. ...
Theresa Payton, CIO for the White House Office of Administration, said in her prepared statement that the incoming Bush administration transitioned from Lotus Notes to Microsoft Exchange over a two-year period from 2002-2004, and that the ARM System established by the previous administration did not work properly with Exchange.
"ARMS was a custom-designed application," Payton testified, "and I understand that it was discovered that it just could not be effectively integrated with Microsoft Exchange."
As a result, thousands or even millions of e-mail messages to and from White House officials -- many of them generated during the crucial period in the run-up to the invasion of Iraq, in March 2003 -- have proven to be irretrievable.
