Cannot add email account back after deletion on macOS Mojave

You are a saint just for replying so quickly!! After trying fifty times, it finally worked a second ago. The only thing I did differently was to put my user name in without the @__________ where it said "user name". I am unsure if that did it or if God just gave me a blessing and let it work. I'm in-it's working! Thanking God for people like you willing to help though. Someone on here with a totally different internet carrier than mine had mentioned that that's how it works with their provider but unfortunately I read through a lot of these and I'm unsure if that is what worked. Thanks again. I feel noticed. (Apple robot had me delete it today July 14, 2026 and that's when all the fun began. It was not a person.)
