Tip
If you want multiple people to manage email sent to a single email address like info@NodPublishers.com or sales@NodPublishers.com, create a shared mailbox. To learn more, see Create a shared mailbox.
Add email aliases to a user
You must have admin permissions to do this.
In the admin center, go to the Users > Active users page.
On the Active Users page, select the user > Manage email aliases. You won't see this option if the person doesn't have a license assigned to them.
Select + Add an alias and enter a new alias for the user.
Important
If you get the error message 'A parameter cannot be found that matches parameter name 'EmailAddresses,' it means that it's taking a bit longer to finish setting up your tenant, or your custom domain if you recently added one. The setup process can take up to 4 hours to complete. Wait a while so the set up process has time to finish, and then try again. If the problem persists, call Support and they will do a full sync for you.
Important
If you purchased your subscription from GoDaddy or another Partner, to set the new alias as the primary, you must go to the GoDaddy/partner management console.
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.
When you're done, choose Save changes.

Outlook desktop will use her primary email alias. For example, let's say a message is sent to Sales@NodPublishers.com, and it arrives in Eliza's inbox. When Eliza replies to the message using Outlook desktop, her primary email address will appear as Eliza@NodPublishers.com, not Sales@NodPublishers.com.
In the admin center, go to the Users > Active users page.

Sending email from the proxy address easily

A new feature is rolling out in April 2021 that allows users to send from their aliases easily when using Outlook on the web. When the feature rolls out to a tenancy where the tenant admin uses the Set-OrganizationConfig -SendFromAliasEnabled $true
cmdlet, users within the tenancy will get access to a list of checkboxes where each entry corresponds to an alias in their Outlook settings. Selecting an alias will make it appear in the From dropdown in the Compose form.
