How to Set Up an Email Alias in Microsoft 365

An email alias is an added email address associated with a Microsoft 365 user's primary email address. A primary email address is typically assigned to a user when their account is added.

As an administrator, you can create aliases for users in Microsoft 365. You must have Global Admin rights to do so. For example, if Jane has the email address [email protected], but she also wants to get emails at [email protected], you can create an alias so both email addresses go to her inbox.

How to Add an Email Alias

Follow the steps below:

1. Access Microsoft 365. For instructions, please see How Do I Access My Microsoft 365 Account?
2. Once you have accessed Microsoft 365, click the App launcher on the top-left corner of the page, then select Admin.

3. In the admin center, go to the Users tab and select an active user from your list of users under the Name column.

4. Next, click Manage username and email. This option will only be available if the user has a license assigned to them.

5. Select + Add an alias, then enter the new alias for the Microsoft 365 user. 
6. Once completed, click Save changes.

Allow up to 24 hours for the new alias to fully populate across Microsoft 365. The user will then have both a primary email address and an alias. For example, all mail sent to Jane's primary address, [email protected], and her alias, [email protected], will go to Jane's Inbox.
