Many people couldn't find how to disable junk filter on Hotmail. Hotmail has two junk email settings - “Standard” and “Exclusive” there is no option to off the junk filter.
Here is the trick, I found in Hotmail’s options there is a item to set up “Rules for sorting new messages”. It appears if an email matches one of these rules, the rule is enacted without running the spam filter. So the spam filter can be disabled by adding the following rule: Move messages to Inbox if sender’s address contains “@”.
That's it! :-)
