Question

How can I add a secondary email address to a user account?

Answer 

A user account can contain multiple email addresses. Each time you add an email address, a verification email is sent to that address and must be confirmed before the email address is valid.

To add a secondary email address to a user account

1. In Admin Center, click  People in the sidebar, then select Team > Team members.
2. Search for the affected agent, and click Edit.
3. In the user's profile, click + add contact and select Email, then enter the email address in the field that appears.
4. When done, click Save at the bottom right to save your changes.

Note: If you receive the error: This email is already used by... when adding an email, see the article: What does the error This email address is already used by mean? to resolve the error.
