Outlook not removing junk emails from one sender

I'm using Outlook 2016 on Windows 11. Beginning on Feb 17, my email spam folder started blowing up with about 40+ spam emails per day, all on "fake medical" topics -- attempting to sell cures for every medical condition that you can think of, and some you would never think of. Then after a couple of weeks, some of them started appearing in my Inbox, not caught by the spam filter. So, I raised my Junk email filter level to High. And whenever an unwanted email still gets through to my Inbox, I put the sender on the Outlook "block sender" list.

But emails from one particular sender keep getting through to the Inbox, no matter how many times I block the address. What else can I do?

    Any chance that the Spammer is using different subdomains in the email address for each email?

    e.g. abc.example.com  @def.example.com

    These will get past even a domain Blocked Senders of example.com because a domain block has to match everything after the "@".

  • If it is from one specific sender, verify that it didn't land on the Safe Senders list by accident. Also, if there are other addresses on the To line, make sure these aren't marked as Safe Recipients.

    If that isn't the case, you can also create an Inbox Rule to delete the message or to move it to your Junk Email folder;
