This article illustrates how to send as a domain/user alias in Outlook 2013. If you have user aliases set up for your account, this section describes the steps necessary to send email from the alias names.
For more information, please read the differences between a user alias and a domain alias. If you do not have an alias name for your account, please contact your company network administrator to set up an alias.
If you understand what an alias is, the next question is "How do I respond from different email addresses?" The steps below describe the set up process in Microsoft Outlook.
