This tutorial demonstrates how to configure Thunderbird on Windows or Macintosh for @colorado.edu Gmail accounts.
You may need to enable IMAP for your account prior to configuration of your email client (https://mail.google.com). To do this:
Your email will be configured and messages wil begin syncing.
Some users may need to change their app security settings when using non-google or android email programs. While signed into your Gmail account in a browser, open the Google Apps menu, then select My Account.
*Note: You should try to connect your account without changing these settings and change only if the previous steps don't work.
*Note: For users using two-step verification, you may need to authorize the app or device the first time you use it to sign in to your Google Account by generating and entering an App password. Visit Google's App Password Help page for more information.
