Organizations who use Exchange server typically develop checklists or procedures for day-to-day maintenance operations. This includes updates, backups, security, disaster recovery planning, etc. Sometimes, new Exchange orgs cobble together these checklists based on other server platforms already in place, or from colleagues at other organizations, online materials, etc. Microsoft has made available several checklists for each version that will allow an organization to provide comprehensive checklists for maintaining Exchange. These can be used as-is, or customized for each environment.
