Explains what the emails address is for a GSuite UIC account
Everyone at UIC has a UIC email address of the form: NetID@uic.edu. For Ada Byron, whose student NetID is abyron1, this is: firstname.lastname@example.org. This is an important email address, because all official UIC email will be sent to it. But it is just an email address; there isn't an email account to go with it. At some point or other, you will have to select an actual email account to receive and manage your NetID@uic.edu email.
Will your NetID@uic.edu email go to your GSuite at UIC account?
Your GSuite@UIC account also has its own direct email address: NetID@gmail.uic.edu.
