There are a lot of legitimate email addresses that cannot be received through outlook. Even when I send a message first and they reply. Completely unacceptable. No way to add them to a trusted list to make them ok to receive. Also, recently started to send multiple notifications of emails being received even after I have read them and deleted them. Additionally, when I mark emails as phishing and junk, they allow them to my inbox still. What is the point of marking them spam?
