This article is for Office 365 global admins who have business subscriptions. It's not for home users.

A primary email address in Office 365 is usually the email address a user was assigned when their account was created. When the user sends email to someone else, their primary email address is what typically appears in the From field in email apps. They can also have more than one email address associated with their Office 365 for business account. These additional addresses are called aliases.

For example, let's say Jenna has the email address jenna@contosoco.com, but she also wants to receive email at jen@contosoco.com because some people refer to her by that name. You can create aliases for her so that both email addresses go to Jenna's inbox.

You can create up to 400 aliases for a user. No additional fees or licenses are required.

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.

Use the new admin center to add an email alias to a user

The new admin center is available to all Microsoft 365 admins. You can opt in by selecting the Try the new admin center toggle located at the top of the Home page. For more information, see About the new Microsoft 365 admin center.

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

  2. 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.

  3. 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 Office 365.

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

  5. Wait 24 hours for the new aliases to populate throughout Office 365.

    The user will now have a primary address and an alias. For example, all mail sent to Eliza Hoffman's primary address, Eliza@NodPublishers.com, and her alias, Sales@NodPublishers.com, will go to Eliza's Inbox.

  6. When the user replies, the From address will be 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, her primary email address will appear as the sender, not Sales@NodPublishers.com.

If the problem persists, call Support and they will do a full sync for you.

  3. In the text box under Alias, type the first part of the new email alias. If you added your own domain to Office 365, you can choose the domain for the new email alias by using the drop-down list. Then select Add.
