FAQ > Questions > How to configure your Outlook client to send out e-mails from a secondary e-mail address using Office 365

Search the FAQ for entries containing:

Even though you can configure Office 365 to receive e-mail from multiple domains (john@primarydomain.com, john@secondarydomain.com, john@tertiarydomain.com), there is no easy way of being able to send out e-mails from one of your alternate domains. Office 365 by default only allows you to send out e-mails from your primary domain.

The procedure below will configure a secondary e-mail address so that you will be able to select at the time of sending, which e-mail to use for that message. Your primary e-mail address will not change with this procedure (if you do want to change the primary e-mail address please send us a support request here).

Please note that this procedure will only work if the secondary domains have already been configured in your Office 365 configuration.

 

 

  1. Open Outlook 2010 and select File, Account Settings.

    If you are using Outlook 2007 go to Tools, Account Settings.

  2. This will open the account settings dialogue. We will create a new account, click on the New... button towards the top of your dialogue.


  3. The Add New Account dialogue will appear. Click on Manually configure server settings or additional server types towards the bottom of this dialogue and then click Next
    If you are using Outlook 2007 select Microsoft Exchange, POP3, IMAP, or HTTP and then click Next. After that select Manually configure server settings or additional server types and then click Next.

  4. The Choose Service dialogue appears. Select Internet E-mail and click Next.


  5. Enter the following information in the Internet E-Mail Settings dialogue:

    Your Name: Enter your full name e.g. John Thompson

    E-Mail Address: Enter your secondary e-mail address (this would be the additional e-mail that you want to be able to send out from) e.g. john@secondarydomain.com

    Incoming mail server:  Follow the procedure here to find out what your incoming mail server (also called your POP server) is. 

    Outgoing mail server (SMTP):  Follow the procedure here to find out what your Outgoing mail server (also called your SMTP server) is.
