My Outlook inbox is suddenly getting a ton of spam and I don't know how to stop it

As and others said in various forums these spams started when giant leaks happened from various hackers in some sites. They sold the emails addresses (microsoft email addresses too) to others and then started the massive spams. Probably there are and others leaks and hackers sold more emails addresses with the result users to have more spams.
On sites that had or have software of microsoft the responsibility is to those admins of those sites and microsoft. To admins because they didn't take enough security measures with security software and do updates to close holes of programs. To Microsoft because its software had or has vulnerabilities.

Of course there are and suspicious sites and suspicious programs that used your emails for spam when you inserted them for subscription or they sold them to others for spam.
It is a constant battle..

I am unable to do blocking for any of them. These emails are coming in so fast and I can't tell which emails should be read. This is crazy, it just started today and they won't stop coming in. It's buried really important emails now and it will take me hours to find them.

I have been reporting phishing for months in the hope they would stop or microsoft would do something about it, but no they still keep coming. MICROSOFT please help???

So agree. It has been escalating since Oct. 2023. In addition protected emails are not coming to my inbox (I've checked to make sure they were in my safe senders but I still don't receive them) and now I find that in order to move from folder to folder, i.e. inbox or Junk to deleted, I have to exit and open outlook again (I have brand new everything so it isn't an equipment problem). Of course when I get on the Microsoft "Q&A Page" I am asked to get Microsoft 365, which I already have. Hopefully these are temporary problems that they will address earnestly.

Welp... so far my hope that Microsoft will do ANYTHING to help us all. This is my first comment, and like others, since about October 2023 my spam box has exploded with spam. For many weeks I have tried to report and block them, but the problem is only increasing! My email address is over 20 years old, and previously I'd get about 3 spam mails a day. Sometimes more, but blocking them would decrease the issue.

Currently, in barely 24 hours I have received 70 SPAM MAILS!! Sometimes they drown out a legit email I have been expecting.

The majority of spam mails have subject names like "Netflix", "Life Line Screening", "McAfee", "Carshield", "Easy Canvas" and pick-your-flavor stuff about packages.

Blocking has had no use, and apparently, contacting them neither. Congrats Microsoft, after decades of using your service, your negligence has made it unbearable, and I'm looking for a new provider.
