The Registrar provides the data which grants students eligibility for UNIs and email IDs. You will not be able to activate your UNI and email ID until data about your status as a student is in place. Once it is, you'll be able to activate your ID online.

If you try to activate your ID before your data is in place, you will receive an error suggesting that you don't exist. Please wait at least a day before trying again. Most incoming students will be able to activate their IDs sometime during the summer before arriving on campus, but the precise timing is not always predictable.

Human Resources provides the data which grants employees eligibility for UNIs and email IDs. Since there can sometimes be a delay before that data is in place, you should contact your departmental administrator (DA) to get interim eligibility via a departmental data feed called Delegated Identity Administration (DIA). After your DA has entered your information, you will be able to activate your UNI and email account online.


If you activated your UNI in the past, then you will just need to ensure that you remember your password. If you have forgotten your password, visit and click on "Forgot Password?" You may also need to activate your LionMail account if you are not a student. Visit and click on "Activate UNI or Email" to activate LionMail.

Your account has been set to expire because you no longer appear in the database of current employees provided to CUIT by Human Resources. If this is an error, please ask your departmental administrator to help you update your status with HR.
