•User principal

A user principal is an account assigned to an individual in your organization. Each individual must have at least one account. You may choose to add multiple accounts for one individual if you intend to use the accounts for different purposes. Use the instance parameter of the principal name to designate the intended use of the account. Following are the special categories for user principals:
