How to Add an Email Alias in Office365.

Last updated on May 5th, 2021

If you want to add an Email Alias on your existing Office 365 email account, then continue reading this guide. Office 365, gives you the ability to create multiple email aliases for free, in order to receive emails from multiple email addresses on your primary email account.

An Email Alias, is an additional email address that can be associated with your current email account. For example, if you want to give to your customers a generic email address (e.g. 'sales@yourdomain.com'), then you can associate that generic email address with your primary email address, in order all the emails send to that generic email address to appear (received) on your mailbox of your primary email address.

Keep in mind that by default, an email alias will use your primary email account settings to send emails, which means that when you want to reply to an email message received on the email alias, the email will be sent using your primary email account settings and your primary email address will appear in the 'From' field.

If you want to bypass this default behavior, and to "Send as" with the email alias address, you can Set up Outlook to send email messages as this alias (after following the instructions in this tutorial), or to use one of the following alternative methods instead:
