Your UNI is not yet in the system. The system creates your UNI after the Admissions department (in your school), your academic advisor, and the Registrar's Office complete the admissions process.

We receive information, on a daily basis, from Human Resources and the Student Information System regarding people who are entering or leaving the University. When that happens, your account will be created and you will be able to activate it.

Once this is done, you can access your email either via our web-based program, CubMail, or by using one of our supported programs (found at http://www.columbia.edu/cuit/software/email.html).
