Hi, JackAtherton1.
I'm Jen, I'm also an Outlook user just like you. I'm not working for Microsoft but I'd be happy to help you figure this out.
I understand you received a suspicious email requesting payment. It's also good to know that you did not engage in the transaction. I've seen an article about this and it looks like you're not the only one who experienced this. You can also check the article that I shared below.

Feel free to share how it went.
