Add an email alias for a Microsoft Office 365 user

Overview

This article is for Microsoft 365 administrators who have business subscriptions (not for home users). If you are not an administrator and would like aliases added to your 365 emails please send an email to and we will be able to assist.

An alias is a way to disguise another Microsoft 365 email address. Everything sent to an alias email address is actually received in the primary email account’s inbox. Aliases can diversify a single email account without having to pay for multiple inboxes.

Add email aliases to a user

1. In the admin centre, go to the Users > Active users page.

2. On the Active Users page, select the user > Manage username. You won’t see this option if the person doesn’t have a license assigned to them.

3. Enter the new Alias and choose the domain then select add.

4. When you’re done, choose Save changes.

5. Please allow up to 24 hours for the new aliases to populate throughout Microsoft 365.

The user will now have a primary address and an alias. For example, all mail sent to Conetix’s primary address, , and the alias, , will go to Conetix’s Inbox.
