Hi Andy,
If you're unable to send or receive email using the native email client on your device, it's possible it has something to do with your credentials or account settings. When you set up your email account on your device, it will automatically use
the correct email account settings from your email provider.
Since your email is working on a different device, we can say that this issue is not account related. You can also check if there are any pending updates for your mail app. Keeping your app and device up-to-date ensures that you have a new and
improve features.
Moreover, to make sure that your email server settings are correct, compare the settings on your mobile device to the settings for your email account on your computer. Any changes
to your account like password change will affect how your email works.
