Add email aliases to a user

Add email aliases to a user

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

2. On the Active Users page, select the user you want to manage.

3. Under Aliases and select Manage username and email. You won't see this option if the person doesn't have a license assigned to them.

4. On the Manage username and email page, add the new alias in the Username field, select a domain and choose Add.

   Tip

   The email alias must end with a domain from the drop-down list. To add another domain name to the list, see Add a domain to Microsoft 365.

5. When you're done, choose Save changes. It usually takes about 24 hours for the new aliases to update.

6. The user will now have a primary address and an alias. For example, all mail sent to [e-mail], and her alias, [e-mail], will go to Jenna's inbox. When the user replies, the From address will depend on her Outlook client. Outlook on the web will use the alias at which the email was received. Outlook desktop will use her primary email alias.
