Huawei P20 Pro

Android 8.1

I can't send and receive email messages on my Huawei P20 Pro Android 8.1

Cause 1 of 4: The incoming or outgoing mail server isn't available

Depending on which mobile network or Wi-Fi network you're connected to, your provider's email servers may be unavailable.

Solution: Contact your email provider for the correct settings for the incoming or outgoing server.
