What Are Conflicting Accounts?
A conflicting account exists if a user created a personal Google Account with the same email address username as their organization-managed Google Apps account. Conflicting accounts most commonly occur if your users were logging into Picasa Web Albums, Blogger, or any of these other Google Applications, before the organization implemented Google Apps.
What happens to conflicting accounts?
After you create new Google Apps users with conflicting accounts, they will be prompted to rename their Google Accounts upon next sign-in. We strongly recommend that you do not delete any conflicting accounts. All data within the Google Account will remain in the account when it is renamed. Please note that users have full control over the rename process; administrators do not participate in this process.
Google Apps email addresses which were added as alternate email addresses of personal accounts will simply be removed from the personal accounts and users will see notification of this change the next time they sign-in
How to Resolve Conflicting Accounts:
You have two options to resolve conflicting accounts:
Create the username in Google Apps and the next time they sign into a consumer product they will be asked to rename their account or change the account type. For example, if Jane has a conflicting account for your company, email@example.com, here are the options she would see when she signs into a consumer product:
Change to an account with a Gmail address (firstname.lastname@example.org or another available gmail name)
Change to an account with a different email address (uses her email@example.com address)
Log-in with a temporary username Google provides (firstname.lastname@example.org)
Note: If your users choose the final option, they will be presented with the same options every time they log in until they choose a permanent solution. Also, the data in their personal accounts will remain safe and accessible to them with all three options.
Ask your users to change their consumer account names before they are added to Google Apps.
Users with conflicting Google Accounts can easily resolve their conflicts by renaming their personal Google Accounts, and the data in their personal accounts will remain safe and accessible to them. Here’s how a user can rename their personal Google Account:
Step 1: Visit www.google.com/accounts and sign in with your personal Google Account
Step 2: Click ‘Change email’ under ‘Personal Settings’
Step 3: Enter a different email address where you can receive mail, enter your password, and click ‘Save email address’
Step 4: Check your other email address and click the link in the verification message from Google to confirm your change
If your users don’t have different email addresses where they can receive mail, they can resolve the conflict by renaming their personal Google Accounts to @gmail.com addresses instead.
If your users have @gmail.com addresses and have added their Google Apps addresses to those accounts as alternate addresses, they will need to remove the alternate addresses to resolve the conflict.
