spam from <preview@***> where the *** part changes each time

Dear OverFifty

thank you for your reply!

My screenshot above is based on the web version of outlook, you can also log in to the web version of outlook to complete the rules and synchronization.

I can understand how you feel when you have this problem and I would love to help you block these pesky spam emails directly! However, the senders or domains that Microsoft blocks are based on the domain information following the "@". That's why you can't use organized senders to block spam you don't want to receive, and the emails you do receive aren't from agreed upon domains or uniform senders, so we can't block them directly. We cannot perform targeted blocking. If a single blocking method is more time-consuming for you, but I hope you understand, you can of course also send this issue back to Microsoft, you can click on Help - Suggestions - to advise Microsoft on this issue!

I wish you all the best

This is the rule:

Not that it would ever do anything, because I understand that rules don't apply to the junk folder.

And I don't see "Sync" anywhere on the screen or in menus.

Dear OverFifty

Thank you for posting to Microsoft Community

I understand your concern, I noticed that the sender always starts with "preview@", may I ask how you set up the rule? I've done a test on my side, as shown in the picture below, may I ask if this is how you set up the rule? (As long as the sender address contains the word "preview", the corresponding email will be deleted), or would you like to share the screenshot of the rule you set up with me?

(This is the path to the outlook.com rule set)

Did you click the Synchronize button to make the rule effective after you set up the corresponding rule? If you don't click the Synchronize button, the rules you set may not be valid.

I wish you all the best

Linda.Wan: This is not a tenable solution. That would result in losing the legitimate emails that are incorrectly sent to junk (it happens often enough to be considered).

I'm not sure this helps. the blocked senders does not allow wildcards or just to look for preview. The spam is getting thru because they are making up fake domain names.

You need to add functionality to allow for wildcards or just looking for a specific word.
