It'd been happening to me as well. I've had my hotmail account for 20 years. The amount of junk email I have been receiving daily is increasing the past few months, it's about 50 per day, sometimes more. Mostly goes into my junk folder but it is such an annoyance and a big concern for me.
For a while I reported and blocked every single one of them, made no difference. I receive a lot of emails starting with preview@..., they seem ads but a lot of them.
Next step, I changed my junk email setting to Strict to receive emails only from safe senders and domains, still made no difference.
Then, I created a rule, emails containing "preview" in the email addresses to be deleted, nothing.
People say, but they go to the junk folder, and? I still have to go through them and save the emails that are not junk so I don't lose important emails.
This is not acceptable. Microsoft should be addressing this issue and providing protection to account users. Why I cannot change my setting to put certain junk emails directly to the deleted folder?
There is no issue for people who use apple computers, no junk at all. My gmail account doesn't receive junk emails but I don't use that account. So I can't really tell but I hear it's not an issue.
Microsoft, please address this problem!!!!!!!!!!!!!!
