FYI there will not be a sufficient workaround to this. The only option that Outlook/Outlook.com support will offer is to increase your spam filter settings, however all that does is just redirect all suspected spam to your Junk folder - which in turn will eventually include real emails. You'll get to the point where you have to sift through hundreds/thousands of junk emails to find those 1-2 real emails so they aren't lost forever.
You are not able to block entire TLDs, so you can only rely on blocking individual domains. However, Outlook has a limit of (I believe) 1,024 domains that you can block. Since most of these spam messages are from spoofed domains, you cannot block them all.
For instance, I just saw over 20 emails from the same spoofed domain. If I were to block all 20 of these domains, I would still get 20 from newly spoofed domains, but I would have taken up 20 of my 1,024 block limit.
The only solution that will solve this is to switch to a different email provider. Changing my email associated with every single account/membership/website is going to be an enormous pain **********, but if I stick with Outlook, the quantity of junk I receive daily will just increase and increase.
We are merely weeks away from 2020, and Microsoft is light years behind Gmail in this capacity. It's absolutely shameful. Get your **** together, Microsoft.
