Remove/Add Account:

There is an error connecting to Google's mail servers. So, remove the account, and then add it back.

1. Go here: Set up Gmail with a third-party email client | gmail help | Google
2. Scroll to: Set up Gmail with Apple Mail
3. Click: Set up Gmail with the Mail mobile app
4. Proceed form there as necessary
