Spam emails with no sender address

My problem is, you have the choice to either report emails or block them. But, on some of them, when you try to use the block option it doesn't show up on some of them. That's because in the email there's no information about who actually sent it to you???? So it can't be blocked. I don't understand how MS lets these emails even go to people. They should be apply to block them period, if there's no email address showing from who's sending it to people

They don't give a damn. There are 133 of us with the same problem looking for solutions and wasting hours. No doubt hundreds of thousands of others, but who say nothing. And we stay. We're not leaving outlook. Only a hundred to complain. Why would Microsoft have anything to do with us? I got to level 2 of support (it took me 3 weeks). It's been a year and my spam filter ("only contacts") is still impossible to activate. They told me they would get back to me, but nothing. They don't really give a ****. That's all.

Why don't they do anything about the many, many fishing emails coming into our junk folder?

Because they don't give a toss.

I spend hours every day looking in junk mail to make sure somebody is not in there by mistake. I use to spend most of that time blocking domains which is futile.

I still search for good ones but just block everything now other than ones that aren't supposed to be there. At the end of the day I delete everything in the DELETE folder which always approaches 200 entries.

I added the *delete all emails except if the sender address contains* "@" rule days ago and I still get emails with no sender address. So it doesn't work. So why are you spamming all these replies here and patting yourself on the back if you didn't even test your own suggestion?

Clearly Outlook is a horrible email service if it allows millions of spam emails with no sender address to be sent to millions of people. Clearly Microsoft doesn't care if they don't even reply to any of these threads. What really upsets me is that while they do absolutely nothing to prevent this massive amount of spam, they're actually removing the spammer addresses mentioned in this thread "for privacy" (which is absolutely laughable, apparently they'd rather protect the privacy of the spammers than stop them from being able to spam people)
The only solution is to switch to another email service, one that actually tries to reduce spam emails and doesn't allow millions of spam emails per day with no sender address.
