Using Classic Outlook on Windows for personal email, calendar, and contact management
Hello
Are you saying your email address is a charter.net address, and you are using Classic Outlook email app to receive emails?
If so, can you go to Spectrum/Charter's website, sign into their email address using their web interface, see if the email is received there. By doing this, it helps determine if the issue is between NFCU <> Charter, or is it between Charter <>Outlook email app.
