Delete an email address for a deceased person

Obviously, n9t should be not.

... How can I get rid of her comcast.net email address?

I don't think Comcast/Xfinity will do this for you. But you can achieve the same result. See https://forums.xfinity.com/conversations/email/deactivate-comcast-email/694443436ff1b06ae43192e1?commentId=69457df899d8a96371d30b74.

It seems that would work for my email address, but not hers.

Could you describe what happens when you try to set it up? Where do things go wrong exactly?

No, it doesn't.  Thanks.
