I used to block all the junk emails until I got a message from Microsoft telling me there was no more room for them. I had to empty my blocked senders list. Blocking junk didn't reduce the number I was getting anyway, so now I no longer bother. Instead I leave it and let Microsoft empty the folder after 10 days, by which time there are well over 1000 sitting there! https://learn.microsoft.com/en-us/outlook/troubleshoot/junk-email/outlook-error-over-junk-emial-list-limit
