Add users who have existing Google Accounts
Before you add users to your organization's G Suite domain, you should check if they have a personal Google Account with the same email address that you plan to use for their G Suite account. Two accounts can’t share the same email address. If they do, it's known as a "conflicting account." Learn more about conflicting accounts.
If your users do have existing Google Accounts that might share the same email address as their G Suite account, you have 2 options:
- Option 1: Invite your users to transfer or rename their account (using a tool in the Google Admin console).
- Option 2: Require users to rename their account.
Use the Transfer tool for unmanaged users in the Admin console to handle this process for you.
You use the tool to:
- Check whether any users in your organization have existing personal Google Accounts that would share your organization's email address.
If no one does, you don't need the tool. Instead, go to Options for adding users.
- If there are existing Google Accounts, you use the tool to email those users and request that they transfer their existing Google Account to your organization's G Suite account. Or, they can choose to rename their personal Google Account.
For details on using the Transfer tool, see Find and manage existing Google accounts.
Add users to your G Suite account using the email address that they used for their personal account.
The next time the user signs in to their personal account, they'll be asked to change the email address associated with that account. They'll have the following options:
- Rename the personal account with a new Gmail address.
- Rename the consumer account with a non-Gmail address that the user already owns.
- Sign in with a temporary username that Google provides (for example, email@example.com).
If the user chooses the last option, they'll be prompted to rename the account every time they sign in, until they select a permanent solution (new Gmail or non-Gmail address). Users have full control over renaming their personal accounts—administrators don't participate in this process.
What happens to the user's data when they rename their account?
When the user renames their personal account with a different email address, all data in the user's personal account remains in the account. The data in the personal account remains safe and accessible only to them.
What happens with email aliases when users rename their account?
If the user used their organization’s address as an alternate email address (or email alias) for their personal Google Account, the alias is removed from the personal account when you create their G Suite account. The user is notified of this change the next time they sign in to their personal Google Account.
