You cannot change an email address, you can change the display info, create a new account and/or add a second account.
It isn't possible to change your
username once you've created an
address, but there are some options to
change the way your username is
displayed.
The three ways to do what I think you are trying to achieve (change in the display name) at least change how the display name appears
- Changing the profile information in her Google Profile .
This will affect all Google products.
- Changing it in her Google Account
- Gmail specific under
Settings->Accounts and Import, edit info for all or just her default email address. Switch the option from (your name in Google accounts) to the desired display name.
Edit, saw your updates : Try creating a second account and use the Import option to get mail from her old address.
Update : Use the above settings for the display name. Import the new account FirstName.NewLastName@gmail.com to the old account. Then in your Account and Import settings choose FirstName.NewLastName@gmail.com as the default address to send mail as. Also switch this to enabled as well
Always reply from default address
(currently
FirstName.NewLastName@gmail.com)
This way
- Recipients see the new address
- She will always reply from her new address
- Labels are maintained as the old account is being used.
From here you can slowly make the transition from the old address to the new address since she has over 30 labels.
