Is there any way to disable spam filter completely?

When logged into Outlook.com, click on the gear icon in the upper right and select Options.

Then under Automated Processing click on Inbox and Sweep Rules and delete the rules.

Then under Junk Email click on Blocked Senders and deleted the Blocks

Yeah.  I have moved most of my important email away from  OL.com  and check very few days to make sure nothing important is in the junk mail box.

Yeah neither it has functional spam filter

It's been working for me for years by recognizing 99% of the spam I get as Junk and files it appropriately.

Maybe you should delete all Rules and Blocks and see what happens for a while.

Could you please explain to me how I can delete all rules and blocks?

I would very much appreciate your help, Thanks!

I think I would like to see how that goes, and if my email client can handle it better than Microsoft.

Exactly what I've been trying to work out, but it's like talking to a brick wall trying to get any sense out of Microsoft.

Their stupid spam filter is even sending their own "Bing" <******@e.microsoft.com> to the junk folder! They're censoring themselves!

Now I keep getting "This website has been classified as malicious." blocking by Office365 (?) when I follow perfectly safe links from trusted senders?

So when I go online and log in to Outlook I find my junk folder FULL of important, trusted senders. How long before they delete these? 10 DAYS! So how many have been deleted already without my knowledge, probably hundreds of important emails! Am I supposed to log in online and check this every week??

What a joke, absolute rubbish!
