We are sorry about the spam mail you’ve been receiving. We are looking into improving the filtering.
Thank you for reaching out to us. We are sorry that you haven’t been able to block certain contacts. We are considering bringing this ability to outlook on the mobile browser. However in the meantime you can do this from outlook.com on a desktop or a laptop. Follow the steps mentioned here https://answers.microsoft.com/en-us/outlook_com/forum/all/how-do-i-block-the-email-of-someone-harassing-me/d2d4a775-b8c8-4c38-bcc6-404a940030e8.

Hi, is there any way to block Spam IDs with/without opening the email? I am unable to find that option in the app or on the outlook website.
