Why am I suddenly getting so many spam emails on outlook.com from an apparent AI bot?

In the past 2 hours alone, I have received at least a dozen spam emails written in random words. For example “isnt a said tone Then it level in very he possible 54 u443 hkother” They are coming from apparent one-off gmail, live, hotmail, and other accounts. And the so-called junk filters are catching NONE of them. I get most of my email on mobile devices, so I’m not using the desktop Outlook app, and thus I can’t adjust the level of spam filtering. To be honest, I pay for Microsoft 365 and I find it ridiculous that (A) the default outlook.com spam filters are not catching them, and (B) I can’t adjust the spam filter so it does catch them. Microsoft, quit dinking around with AI on Bing and put it to work in your own spam filters!
