If the user has multiple addresses, then the primary email address SHOULD be returned in the Autodiscover command response. The primary email address is the address that appears on the From line when a user sends an email message. This address can be the same as the email address that was sent in the request. The client device SHOULD record the address returned by the Autodiscover command response and SHOULD use this string value for all additional communication.
