Before you setup up your New School Mail on a mobile device or mail client, you must first enable IMAP in your New School Google Apps:

Sign in to your account at mail.newschool.edu.

Click the gear icon in the upper-right and select Mail Settings.

Click Forwarding and POP/IMAP.

Select Enable IMAP.

Configuring POP or IMAP access for your New School Google Apps email address is very similar to configuring it with a Gmail account. However, any time you're asked for your username during the configuration process, you'll need to enter your full email address (YourNetID@newschool.edu).

Google provides step-by-step instructions for all supported mail clients and mobile devices. Review the lists linked below to find instructions specific to your device.
