Undeliverable Email - Time Warner Internet

This question is about "Undeliverable Email", with Time Warner Cable internet and apps. Years ago when I first got Microsoft Outlook, I set it up for my email to automatically forward my home email to my email address at work. Now that address is no longer available, everyone who sends me an email gets an error back saying that it was undeliverable. I get their email but they think I don't because of the return error, trying to forward it to the old work address. I first tried to update the email address in Outlook but that didn't solve my problem so I deleted the rule for the forwarding, and that didn't work either. I have Pro Plus 2016.

Do you have anything else I can try? Microsoft was no help at all.

Thx for any help you can give me.
