While most students have email addresses ending with "," you will notice that some Law School students have email addresses that end with "" The "" addresses are either email accounts on the Law School email system or Law School forwarding addresses.

Incoming students receive a "" address that automatically forwards to LionMail. There is no need to configure this address, the address is hardwired to send all mail to your LionMail account. Students can look up their full name email address in LawNet.

Please note, student full name email addresses expire on July 31st of the year you graduate. On the other hand, your LionMail account and address lasts forever as your lifelong alumni email. Reminders about the expiration of the "firstname.lastname" email address will be sent as the expiration date nears.

  • You must create a device password to use LionMail with your mobile devices and software clients
  • The same device password must be used on all your devices and software clients
  • This device password will be different from your UNI password
