In this blog post, you will learn the steps on how to create Email Aliases for Microsoft 365 User using Microsoft 365 Admin Center.

What is Email Alias Address?

A primary email address in Microsoft 365 is usually the email address a user was assigned when their account was created. They can also have more than one email address associated with their Microsoft 365 business account. These additional addresses are called aliases.

An email alias is a secondary email address that connects with a user’s existing account. Any email message delivered to an email alias is sent to the same mailbox as the primary account. You can create up to 400 aliases for a user. No additional fees or licenses are required.

As a Microsoft 365 admin, you can add additional email addresses to your user’s accounts by creating an email alias. For example, if customers have questions, they can email [email protected] instead of [email protected], which looks much more professional.

The user who is using this email address as their alias will get the email directly in their inbox. When they reply to the mail; however, they will reply with their primary email address.

If you want your people to reply with the email address [email protected] instead of [email protected], we recommend that you create a shared mailbox. (Put a link to Shared Mailbox Article).
