I use a hotmail email address and I've been getting multiple spam emails a day and they don't have sender addresses. If I try to reply to them, Outlook would tell me the recipient cannot be empty. I also cannot block them since there's no sender addresses to block.
This is getting extremely irritating.

Don't try emClient. As far as I can tell it won't even allow me to Block. Outlook will but only on real emails. I have tried the free version of emClient not the paid one. The Outlook mail is use is the one on W10/11. Again free version.
I have the same problem. multiple emails per day to inbox. No email address. Not able to block, I constantly report as junk and pishing, as most are from a bogus anti virus provider telling me my pc is infected.
Are you saying to click reply to see the sender address and use the address to block??
I have tried doing this, but it doesnt work. I am getting smashed with 60-100 spam emails a day. I am missing very important information in my email. It is beyond frustrating.
Using the Previous Mentioned Action of Viewing Message Source & Creating a Rule which Includes the email Address in the <> "Does Not Work". In Addition, I have also Copied & Pasted "Every" email in the Message Source, Copied & Pasted in my Blocked Sender's Section in Outlook. Still does "Not" Work. This is Driving me Insane.
I created that exact rule and it doesn't stop those annoying emails with no sender shown. I'm still getting them and all I can do is delete them when they come in.
