U-Mail account services -- and the various electronic services affiliated with your UCSBnetID -- funded primarily by tuition and are meant as a provision to registered students. As such, we at U-Mail don't have the authority to grant account extensions.
If you have some continuing relationship with the University for which you believe your account should remain active, you'll need to get authorization from the Office of the Registrar (undergrads) or Graduate Division (grad students). To keep your account active, you'll need to obtain documentation from one of those offices demonstrating this relationship, along with the duration for which your account will need to remain active. Once you've delivered this documentation to our 4101 SAASB we can process an account extension for the duration specified. You can obtain the form required on our website here.
