<p>Well, I'm not at NU yet, but I guess I can loan a helping hand.</p>
<p>You have to change your alias.</p>
<p>The following has been copied and pasted from one of my previous posts:
When you click on "Set up email forwarding" on <a href="http://www.northwestern.edu/webmail%5B/url%5D">www.northwestern.edu/webmail</a>, it leads you to NUIT (<a href="https://snap.it.northwestern.edu/it/mailtools/%5B/url%5D">https://snap.it.northwestern.edu/it/mailtools/</a>) and on the left module under E-mail, click on "Change Northwestern email address" and if it prompts with a box for authorization, you use your NetID and (email) password. You are then put in a page with two options. Choose the first one (Edit Your Directory Information) and then you change your email alias.</p>
