Problem
When signing up to Google Workspace if the admin email address is already in use because it is associated to a Consumer Google account and error appears.
admin email is already in use
Environment
- Google Workspace sign up page
Solution
- Sign up using a different email address in a domain that is not in use, for example username1@domain.
- Proceed with the domain ownership verification as instructed in Protect your domain.
- Rename administrator user account to the original email using the steps described in Change a user's email address.
Cause
There cannot be two Google accounts associated with the same email address, for this reason, when you try to create a Google Workspace account, if one Google account already exists with the email address you try to sign up with, it is expected that it gives an error saying it already exist or it is being used by a Google account.
