Your primary email address in Office 365 is usually the email address you were assigned when your Office 365 work or school account was created. The primary email address could also have been changed by you or an admin at your organization. When you send email to someone else, your primary email address is what typically appears in the From field in email apps. You can also have more than one email address associated with your Office 365 for business account. These additional addresses are called aliases.

For example, let's say Eliza's primary email address is Eliza@NodPublishers.com. She also wants to receive email at Eliza.Hoffman@NodPublishers.com and Sales@NodPublishers.com. You can create those aliases for her, and all the mail sent to those aliases will go to Eliza'sInbox.

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 shared mailboxes in Office 365.

Add email aliases to a user

You must have admin permissions in Office 365 to do this.

  1. In the Office 365 admin center, go to the Active users page, or choose Users > Active users.

    In the Office 365 admin center, go to the Active users page, or choose Users > Active users.

    In the Office 365 admin center, go to the Active users page, or choose Users > Active users.

  2. On the Active Users page, select the name of the person you want to edit.

  3. On the right, in the Username / Email Aliases row, choose Edit.

    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 for Office 365 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.

  4. On the Edit email addresses page, 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 choose Add.

    Note:  The email alias must end with a domain from the drop-down list. To add another domain name to the list, see Adding additional domains to Office 365.

    The Edit email addresses and username pane showing the primary email address, and a new alias to be added.

  5. When you're done, choose Save.

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

    The user now has a primary address and an alias. All mail sent to Eliza@NodPublishers.com and Sales@NodPublishers.com will go to Eliza's Inbox.

    This user has a primary address and two aliases.

  7. 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.

Did you get "A parameter cannot be found that matches parameter name 'EmailAddresses"?

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 for Office 365 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.
