somehow I have blocked a newsletter from my MSN account - it has several other email newsletters attached to the original publisher

I can not find it on my blocked list

I can not find it on my safe list - added it but still blocked

I have been using my Yahoo account to re-direct the emails but do not understand why I can not get them in Outlook  - I have written the company several times but of course they can not reply to me as it goes into LaLa Land

What am I to do ??? at my wits end and can not find the answer
