It is the content of each message that is important. If a particular message would have been filed as a paper memo, it should still be filed (either in your email program or in your regular directory structure), and it should be retained the same length of time as its paper counterparts. It is inappropriate to destroy email simply because storage limits have been reached. Some examples of email messages that are public records and therefore covered by this policy include:
• Policies or directives;
• Final drafts or reports and recommendations;
• Correspondence and memoranda related to official business;
• Work schedules and assignments;
• Meeting agendas or minutes;
• Any document or message that initiates, facilitates, authorizes, or completes a business transaction;
• Messages that create a precedent, such as issuing instructions and advice.
