Problem
How can you add a domain when you have encountered the error message This domain is already in use while signing up for Google Workspace account? This also may happen when adding it as a secondary domain, or user alias domain.
Environment
- Admin console
Solution
- Use the Admin Toolbox to fill out this form to free up your domain and be able to use it with your new account: Domain in use contact form.
Cause
Another account currently uses the domain you want to register. Domains can only be linked to one Google Workspace account at a time.
