There is currently a bug we are working on where students may see a warning from the Registrar or in Identity Manager that they do not have U-mail. Please ignore these warnings. Every student who activates a UCSB netid gets an account at gmail. You can log into gmail with your email@example.com and your UCSB password. A U-mail alias is automatically added to your account and your default email is set to firstname.lastname@example.org
Sorry for the inconvenience.
