Changing the email alias of your (Microsoft 365) account

When your @northwestern (Exchange) account is initially created, it has a default address of "", where "firstname.lastname" is the alias. Your initial email alias most often will reflect your legal name.

To change or enter your email alias to reflect how you would like it to be displayed in University systems - if that is not your legal name - follow the steps below. Email sent to your previous alias will forward to the new address.

To learn more about how to use the different name, pronoun and email fields, whom to contact for support and more, visit Institutional Diversity & Inclusion's Frequently Asked Questions page.

Your Sent From address in Exchange is automatically updated to reflect your new email alias. This change should be reflected in Outlook Web App within 15 minutes.

  • Note that if you are using Outlook for Windows or Outlook for macOS, you will need to remove and recreate your account within Outlook to reflect this change.
