Try these basic troubleshooting steps first

1. Tap Safari and attempt to load a webpage (try any webpage). If you can load a webpage, then your device has Internet access. If you are unable to load a webpage,follow these troubleshooting steps.

- Try to use an alternate Internet connection if available:

1. Try a different Wi-Fi connection

2. If your iOS device has an active cellular data plan, tap Settings > Wi-Fiand turn off Wi-Fi.

3. If the affected email account is provided by your Internet provider, see if your issue is resolved while connected to your home Wi-Fi network.*

2. Log in to your email provider's website to ensure that the account is active and the password is correct.

3. Restart your iOS device.

4. Delete the affected email account from your device.

- Tap Settings > Mail, Contacts, Calendars.

- Choose the affected email account, then tap Delete Account.

- Add your account again.

* If you are only able to use your email account while connected to your home network, this may be a limitation put in place by your email service provider. For further support, please contact your email service provider directly.

Thanks,

Matt M.

Configuration problems with IMAP e-mail on iOS with a non-standard SSL port.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.
