This article illustrates how to send as a domain/user alias in Outlook 2010. 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. Due to the hundreds of email clients available, the settings below should provide a good description of the process for the other applications.
Please contact your network administrator for further instruction. Please note: This can ONLY be performed in Outlook and not in Outlook Web Access. Also, the outbound email for aliases must be sent via POP3.
