Problem
How can you prevent the creation of consumer or unmanaged Google accounts in the domain for the people that have an email address in the domain but don't have a Google Workspace user.
Environment
- Admin console
- User's section
Solution
Solution 1
Solution 2
- Access the Admin console.
- Create a user for every person who has an email address in your domain following these steps.
Solution 2
- Configure your mail server to block the Google sign up verification emails based on the following:
- Envelope from (or Sender): *@idverification.bounces.google.com
- Header from: noreply@google.com
- Subject: Verify your email address
Cause
As long as a user can verify a non-Google email address through email, they would be able to create a consumer Google account (unmanaged account) if the email address they use does not exist in your Google Workspace account.
