Exporting Old (Archived) Tasks

Recently I was needing to extract all activity history to do a mass reassignment of the tasks. I used APEX data loader and the export function to pull out what I thought was all tasks. I noticed that the dates were only dating back about a year.

Apparently items with the following criteria are marked as 'Archived' in Salesforce.

• Events with a create date greater than 365 days old
• Closed tasks with a due date greater than 365 days old
• Closed tasks without a due date that were created more than 365 days ago

In order to pull out ALL activities you need to use the Export All function in APEX data loader. A single export of all activities with no criteria will return all archived and non-archived results.

Here is a link to the Salesforce support question.
