 What is Capstone? Capstone is an approach to managing email records. It's intended to help your agency manage large volumes of email records in an automated way. Under the Capstone approach, most agency employees' email will be retained for a predetermined amount of time. That time period is designed to meet agency audit, legal, and operational needs. At the end of that time, those email messages are deleted. A select number of accounts are identified as Capstone accounts. Those are email accounts for senior officials and others whose actions and email records have historical significance. Capstone officials' accounts are identified and captured for permanent retention. That means they'll eventually be transferred to the National Archives, where future generations will use them to understand your agency's role in our government's history. Capstone is one option your agency has for managing email records. Your agency records officer and records management team can tell you more about how email is managed in your organization.
