Step Six
Setup is complete! Upon completing these steps your email account should be ready for use in Windows 10 mail. Please test your new account settings by sending a message to yourself and if you have an alternative account try sending a message to that account and then reply back from the alternative account to your new mail account to confirm send/receive is working as expected!
