Hi I currently am unable to mail myself within Thunderbird using outlook.com Problem only started a few days ago. I receive the following message

Your message wasn't delivered because the recipient's email provider rejected it. Remote Server returned '550 5.7.520 Message blocked because it contains content identified as spam. AS(4810)'

I also use a gmail account within Thunderbird & this presents no problem, allowing me to send gmail to gmail & also gmail to outlook & outlook to gmail. I have also noted that if I log in to outlook via a browser I can send outlook to outlook with no issues but not from within Thunderbird. Not a huge problem in the great scheme of things, but I do mail myself quite often with links & reminders etc so would be good to get it sorted. Any help much appreciated Thanks Neil

Have you asked your provider (outlook.com) why they are doing this? I suggest you "email yourself" using another account as from:. Then the outlook spam filter will leave you alone.
